Gerpin

Gerpin, possibly a derivative of slurpin and gulping, implies one is doing a majestic job of playing the skinflute. This show of talent is often noisy, vigorous and messy. Can be used in a derogatory sense to mean someone is player hating, or generally talking an obsessive amount of shit.

“Shawty came to throw neck last night... moe when I say she was GERPIN”.

or (derogatory)
“Man always got my name in his mouth. Stay gerpin me.”
