look up any word, like sex:
 
1.
To suck ones fart through a straw. Commonly takes place at drunken orgies during foreplay, but occasionly has been known to happen at family parties. Sometimes a residue is left in the straw and vomiting is imminent. Further inhalment ensues in practically eating excrement.
Guy 1 - Hey... what the fuck areyou doing? get that straw out of my ass!

Guy 2 - Chill Grandad, i was just partaking in an act of Gaseous Inhalement.
