"Buff", this word might resemmbles to muscular for common people.

But, for the 5 of us (Jemme),

Buff is defined as "JIMMY"

Don't get it? Here's an example.

"Oh Tom, you're so buff !"

Wrong-o !

Correction, "Oh Tom, you're so JIMMY !"

Yeah.

Get the idea?

Buff up = Jimmy up.

Buffing up = Jimmy-ing up.

Buffed up = Jimmy-ed up.

I'm sure you people will get it. =D

-Jimmy-
Superiorness of the superior.
