A spinker is a person who has the background of a chink, spick and nigger.
Booch is the son of Lai Sim and Fred Greg. Lai Sim is a chink, Fred Greg is a spick. Booch is a spick and a chink. If Booch fucks a nigger and has a kid, the kid will be a spinker. Chink, spick and nigger.
The sexual act of lying down on your back with an erection, and having a little person sit on your dick (vaginally or anally). They then lift their legs up, you grab them by the sides, and spin them around super quickly like a Beyblade.
Example
Person 1: Man, I'm feeling so relaxed. Got a three foot tall hooker last night and gave her a MidgetSpinner.
Person 2: Oh yeah, I've heard those are super therapeutic!
