head on collision

The impoverished form of an Irish Car Bomb (Bailey's dropped into and chugged from a Guinness). A head on collision is Kahlua dropped and chugged from a Busch Light.

1) Serve a shot of Kahlua
2) Drop into a cup of Busch Light
3) Chug in one gulp

"-Yo, let's do an Irish Car Bomb.
-Nah, that's too classy, I'll take a head on collision"

thesauric collision 

N. Describes the fairly common occurrence amongst literate types, in which two synonymous or near-synonymous words are spoken somewhat atop each other, resulting in the creation of such phrases as "dramastic", "grood," and "for suretain." While these phrases have been used intentionally, true thesauric collisions only result from accidental construction of such phrases.

While Leeroy was at the cocktail party, he accidentally subjected the words "sweet" and "nice" to a thesauric collision, and thus told the Swedish ambassador to the UN that his expensive new martini glass was "swice."

Latvian Train collision 

A weird sex act involving two people with their assholes facing each other so both holes touch. Each person squeezes out a huge long shit so they both collide like trains coming out of tunnels. Then the people ejaculate and cover themselves in the shit and cum so it looks like the flag of Latvia.

"Jim and I achieved the Latvian Train collision after 10,000 other successful attempts."
