Coined in Toronto Ontario, this phrase has begun to spread rapidly. The phrase essentially means don't try to talk if you can't walk the walk.

Note: There is no stress in the words boop and poop...when pronounced sounds more like bewp and pewp
Hypothetical situation...Someone claims they can bench press 300 pounds when in reality they can only do 200...Response would be: Yo...don't boop if you can't poop.
