Beer farts are the product of drinking too much beer, especially but not exclusively bitter.

They are incredibly smelly and frequent, and make your bum itch.

Beer farts are the worst thing to develop on a date, unless you feel comfortable blaming noxious odours on your partner.
John: "Bloody hell Jim, after those bitters last night I've been farting all morning!"
Jim: "Me too - the beer farts are coming thick and fast!"

What's that smell? Beer farts.

Man: "It's so good of you to agree to go out with me."
{Cue uncontrollable beer farts}
Woman: "Was that you?"
Man: "No you smelly ogre, it was you!"
