Alchwitz 

When you go into a crowded elevator, wait until the doors close and fart.

Of course, just when I have to go to the top floor, someone laysdown an alchwitz.

Auchwitzing 

Farting so bad in the shower you can barely breath

Person 1: Hey I Auchwitzed myself last night and it was terrible bro
Person 2: Why were you Auchwitzing yourself?
