Face Fart
A smelly burp that happens when you stuff your face with greasy food and drink beer like it's water. You burp and it hits you like a slap from a drunk uncle.
After eating deep-fried everything, my face fart was so bad my friend ran out of the room.
At the BBQ, I face farted my cousin and he had to go get a mask.
During the pizza party, I face farted my brother and he said I smelled like a garbage can.
