Wind Dueling 

while you're eating someone else's ass you burp in their ass while they are farting. You two are dueling with your winds and it ends with either your burp going inside their ass or their fart is going inside your mouth.

I was about to beat my girlfriend in wind dueling, but I accidentally threw up in her ass and got disqualified.

Urban Dictionary dueling

When two Urban Dictionary contributors submit entries simultaneously, and each (acting as editor) rejects the other's definition. Then both tweak their entries and resubmit, only to reject each other once again; the struggle may continue like this for hours, or even days. Whoever gets their definition accepted first wins.

I've been Urban Dictionary dueling this Australian twat for the past six hours.
