Dude, seriously that bitch is huge, check out that double crack!

When you are in a car with other people and have to fart really badly you let a little crack go and open crack the windows open very little but increase as you let more fart go
John opened the window a crack every 20 seconds as he was farting a little in between. John was double cracking
