if im in a lift with more than one person, and only one person i know, i have a conversation with them describing something that sounds really really nasty, but then explain it as something not bad at all, example:
yeah, last night, me and nancy were having the hardest time packing my meat into her fajita (say like vagina) so i took some of the juice from my meat, and drizzled it all over her thing, and finally we got it to fit. thats how we make a damn good fajita (say like fa-hita)
