The happy feeling one has before and after hitting the "tripping" phase while smoking tobacco. Characterized by a very relaxed sensation, without the light-headedness of a tobacco high. Most commonly achieved while using cigars and pipes; cigarettes generally lead straight to "tripping".
"Dude, you trippin yet?"
"Nah, I'm just Chimpin. These smokes suck."

and

"Woah man. . ."
"What?"
"Im still chimpin from that cigar."
