1970's Gas Crisis is the term for a sex act in which a length of plastic tube is inserted into the partner's anus, and sucked on. The act is so named because it appears similar to the gas siphoning that occurred during the gas crisis in the 1970's, where people would suck on a pipe to start the flow of fuel from one source to another.
My ass really hurts after last night, but my partner really wanted to experience the 1970's Gas Crisis.

Get the 1970's Gas Crisismug. Large small car with no space inside. Poor performing transmission allows tandems to overtake and holds up traffic whilst guzzling petrol. Usually driven by someone without a clue (that nicer cars exist, or how to drive)

Get the Throwing the 4's Upmug. A couple of short-ass boys and 1 slightly taller 1, about 12-14 yrs old. Very amusing, but a bit townie and childish. Like to squish daddy long-legs's. Hang around on their bikes (hence 'pushbike') and do wheelies and show off, while asking innocent blondes if the could pull them. V. irritating
"Hey Becca, I can't wait to see the Pushbike Dudes this Friday night"
"There were all these pushbike dudes hanging around our school today"
"Belgium is full of pushbike dudes"

Get the Pushbike Dude(s)mug. Sperm Build-up Theory: A girl with a really nice ass, starts dating some guy who is clearly tagging her, and her ass gets much larger, while everything else stays proportionate.
Jessica follows the S-B theory to a tee! She used to be smokin', but since she started dating Mark her ass has become huge! Must be sperm build-up!
