mexican bong 

the act of one placing their mouth snugly around anothers anus as while deeply inhaling an unforgiving blast of tastey flatulence

"susie was being a total bitch so i forced her to take a rip off of the mexican bong."
"oh gregory, i love sucking on your ass and breathing in your delicious bodily pollution."
