Everyone has had one of these faces in their lifetime. You either care, or you don't, and sometimes, or most times, you hope your fart doesn't stink up a room. Here are all the 15 faces of your 'oops, farted' look.

1. When you take a quiet moment during a conversation and let one out silently while you look like you're thinking of what to say next.

2. When you know no one is around, but check around anyway to be sure.

3. When you just can't believe how good that fart was and that's all you can think of without trying to show it.

4. When you're slowly trying to let bit by bit out because you know it's going to make a loud noise and the person you're talking to will definitely hear it.

5. When you just couldn't care anymore and decide to moan because it was the most awesome thing that just happened to you.

6. When you realize it was really loud, but thankfully there's a lot of people making a lot of noise outside, but you're still worried if someone heard that rip.

7. When you pretend to be in a conversation with your friends but you're really concentrating on letting it out and hope that it isn't too warm or wet..

8. When you're halfway talking and it comes out.

9. When you've been found out and all you can do is laugh about it.

10. When you're trying to make everything look normal, but every facial muscle in your face is saying this is going to explode.

11. When you're really hoping no one can smell it because it felt really warm..

12. When you're holding it back in and some came out but you really can't let it all out yet.

13. When you're trying to play it cool, and hope people won't take notice.

14. When someone turns their head over to you because they heard.

15. When someone asks if that was you, and you slowly deny it with lots of guilt in your eyes.
