sinplosion 

An explosion of sin. Refers to excessive “bad behavior” after a time period of abstaining from such behavior. Usually occurs in concurrence with a vacation or some time away from responsibility but not always.

Charlie: We have 2 days left until Christmas break, no work! I've been sober for a week!

Marc: It's true. Get ready for a sinplosion, we're binge drinking for 4 days straight.

Sexplosion 

When the male of a species that uses sex for pleasure has gone without intercourse for such a lengthy time that the resultant discharge is akin to a turbo-powered firehose hooked to a vat of mayonnaise.

After Bobo the Wonder Chimp had been isolated for 8 years, his first sexual encounter resulted in a sexplosion which rocketed the unfortunate female chimp a distance of 200 yards directly into a meat grinder. The silver lining is, the resultant burgers were delicious.

That was so funny I couldn't contain my Laugh-splosion, I think I might have pissed myself a little bit.

Sexplosion 

The climactic end to a sexual encounter. In the case of female Homo Sapiens, multiple may be expected.

So I made the beast with two back last night, and it ended with a giant sexplosion.
