alleyoop 

1)in basketball, to pass to a midair teammate who proceeds to slam dunk the ball. 2)to set up someone else with an easy, quick finsh to a joke.

1) There's Dwyane Wade with the alleyoop to Shaq for the easy finish.
2) "... so apparently me and her are just fuckbudies now"
"what a bitch"
"yeah, fuck her" <---the alleyoop
"occasionally literally" <---the punchline

Allioop 

When you are fucking a girl lying on her back, right before you cum, you pinch her leg really hard. If you time it right, you should be able to aim and make your shot in her mouth; thanks to the setup of the pinch.

Dude, I totally played ball last night with that sexy bitch. I alliooped it straight into her cum dumpster.
