Origins of the word 'lepak'

This is the exact conversation I had with Clare via text

C: hahaha ~ has a major lepak vibe
S: Lol. I ~ed all day
C: haha! omg. Same here :) Screw studying
S: ~ will become the new sign for lepaking. When we wanna saw lepak, we must trace it in the air.
C: Hahaha! We're too cool for school ~ Even highlighting books is tiring to me wtf
S: Haha I am so writing our conversation down.
C: SUA~

Slacker's jargon. I kid you not.
