armplunt 

when you take a tennis ball and you open up your arm and then you put it in and then you stretch the skin over it and then you sew it shut and then it heals over the tennis ball to make it look like you have muscles

"That guy's muscles look fake as fuck."
"Yeah, rumor has it that he got an armplunt the other day."

When you take a tennis ball and you open up your arm and you put it in and then you stretch the skin over it and then you sew it shut and then it heals over the tennis ball so then you have muscles.

Arin gave himself an armplunt in order to make Dan think he was muscular and to impress Suzy.

Arm Plunt 

It's when you take a tennis ball and you open up your arm and you put it in and then you stretch the skin over it and sew it shut. It then heals over the tennis ball to make it look like you have muscles.

Damn, Arin! Where did you get those muscles?

Oh, these are just my arm plunts.
