That may have been a reference to an illicit drug. I'm not sure. I'm a late bloomer.
In any event, it is literal in this case. I found a video of our beloved Naureen kicking some major ass in the boxing ring. Watch her mop the floor with that lightweight Vanessa Norris. Beautiful as a butterfly AND as deadly as a bee. Well bees aren't deadly but you get the reference. The stings do hurt though.
