Don't twist my flippity flaps 

When dick bags try to manipulate your words to make them come off differently.

Phandrew: "I can't hangout with the boys tomorrow, I'm going on a date with Jessica"
Philip: "You're saying you are going on a date because you don't want to hangout with us??"
Phandrew: "Don't twist my flippity flaps Philip!"

When your dick has multiple spasms and goes out of control just like when you finish up giving your boyfriend the biggest blow job ever.

Steven: I loved that blowjob but now my penizzle is flippity flapping.
Joe: You know how we do nigga slice.
