Smokers Thumbs Up 

A "smokers thumbs up" has the same meaning as the regular "thumbs up" but involves a nice twist. Instead of an erect thumb and clenched fist, the smokers way is either: act as if your holding a pipe with a finger over the carborator or rush, but all without the pipe, or act as if holding a lighter, just with out the lighter.

"Dude are your parents asleep yet?"
*Smokers Thumbs Up*
"Aright thanks"
*Ignites Lighter*
