There are an awful lot of stereotypes when it comes to gender. 

Little quirks and assumptions we simply can't shake. Whether it's the belief that men never ask for directions, women take ages getting ready, or that there are boy jobs and girl jobs on Downing Street - many of us are guilty of jumping to conclusions. 

But what if the veil of gender based secrecy is lifted? Thanks to the anonymity of the internet and throwaway accounts, now more than ever people can speak their mind and share what really happens behind closed doors.

So, here are a few things guys say when the female of the species isn't around - according to the good folks over on reddit anyway.

1. It's all a front

"Some dudes have this shitty habit of being a dick to their mates when a girl is around to show off, so they're actually nicer when it's just the guys."

2. And... Sometimes not so much.

"My entire friend groups dynamic revolves around being dicks and heckling each other."

3. Surgically putting a booty on a dog. Seriously.

"I spent four hours yesterday drinking beer and talking to my best friend. The main subject you ask? Debating the merits of surgically grafting ass-cheeks on to dogs. His wife is due any day and the "dog ass implants" are all we talked about. I don't remember at all how we got on the subject, but it never left."

4. If we're being honest, probably mostly this.

"Sports & video games are talked about a lot more, things like family stuff (kids, dogs) far less."

5. The filter is removed.

"The filter comes off.

Jokes get harsher and dirtier. We can make jokes that are counter to our political/social/religious beliefs and laugh at them if they are funny. I can make joke around my guy friends, or at their expense that I usually can't make around women.

Disagreements are usually a lot simpler. We don't worry too much about offending each other or hurting each other's feelings. If a line gets crossed, it gets squashed pretty quick. "Dude, that's not fucking cool. Here's why." "Oh, shit man, I'm sorry. I didn't mean anything by it." "I know man, just watch it." "Alright man. Sorry. We cool?" "Yep."

We make a lot of jokes at each other's expense. We will viciously rip each other apart all night. That being said, if one of us gets into actual trouble we will circle the wagons quick and handle that shit. I have a list of friends that will not hesitate to make fun of my thinning hair or my diabetes that I 100% can count on to have my back when the chips are down."

6. Putting giraffes in places... For some reason. 

"I once listened to a group of guys debate for over an HOUR about how many giraffes you could fit in an RV, provided they were alive going in (but didn't have to be coming out)."

7. Sex. But probably not in the way you would expect.

"If I ever talk about sex with my friends it'll just go something like.

Friend1: Hey, so what did you do last night?

Friend 2: I ended up grabbing dinner and crashing at (girl one of us has been seeing)'s house.

Friend 1: Raises eyebrows

Friend 2: nods

Friend 1: Niceeeeee

And that's really as far as it goes."

"I think you'd be surprised. Obviously every group of guys is as different as every group of girls, but there are some common points.

-We talk less about sex than you'd think.

-A lot of our time is spent telling dumb jokes and being idiots. Every so often I'll meet a girl that can join in on these conversations and it's always a blast. But more often than not, and I'm definitely being sexist, girls will stay outside a bit or a goof with "Haha you guys are so dumb." It's not mean-spirited, but how about a "Yes, and" assist?

When a girl will go along on that joke wave, I know she's cool.

-We don't talk about ourselves in the ways you'd expect. My best friend in the world is named Eric, and I didn't know his birthday for a few years. It just never came up. I didn't know his last name for a year. I didn't know he had a brother until a week before I was best man at his wedding."

8. Sometimes we talk about everything but the important stuff. 

"I have one friend I talk to every morning where I work... known him for a few years now.

No idea what his name is."

9. And finally, everything. 

"There is no limit to the absurd breadth and depth of what is covered in conversation. No rabbit hole is too deep to fully explore."
