Brazilian Gasmask
When a guy sits on your face with his nuts on your forhead and farts real hard, causing your hair, if you have any, to blow back. Leaving behind shards of shit in the persons hair.
"Hey did you hear what happened to Travis today?"
"No, man what?"
"Shawn gave him a Brazilian Gasmask!"
"No, man what?"
"Shawn gave him a Brazilian Gasmask!"
