Cobbin can be a verb. It can be a noun. It can be an adjective. It can really be anything at all. That's the beauty in it. One can cobb. One can go cobbing. Something or someone can be cobbin.
Yo, wanna meet up? We can go cobbin this weekend.
Fucking cobb it man. Cobb the fucking shit out of it.
"you ever been cobbin'?"
"that shit was straight cobbin'"
