To jiggle means to do something that you enjoy, but you do with complete
confidence. Some
even say that need to have a certain amount of
rizz to really jiggle something.
Example 1:
"How's it going, bro?" – "I'm good, bro. I just jiggled the bench
press today." – "Damn, keep on jiggling bro!"
Example 2:
"Ayo bro, wanna jiggle some Fortnite after school?" – "Sure, let me jiggle my
homework first and I'll be online at 2pm."
