To do something cunningly, preferably without any one seeing, apart from your best mate to prove you did it

so like when I'm imagining "sly" I just see a real slick looking dude just posted up against a suspicious building under a shadow.. zoom in and the fucker has a tooth pick in his mouth just so effortlessly sweet

Sly
by Krkič February 15, 2020
A guy I think that is cool and especially funny. He tries to put his grades up and tries to listen to the teacher when explaining a lesson. He sometimes draws but I don't think they're that good. Sometimes he's drawings are random, like sometimes he draws something cool and awesome and sometimes he just draws nonsense.
Sly tries to be cool around his friends and makes you laugh all the time.Sly cares what grade he gets and tries to recite in class. He tries to be quiet in his seat and tries to be obidient.

Me and bros were cruising the broadwalk when this mooleon started trashing my boy Sly. So of course, i beat the dirty moolie's head in until he understood my Guido dominance
