A devious lick is when someone steals an item of great social or political importance. The act of stealing the item must fit the criteria of being either devious, devilish, or nefarious.
Person 1: "It's only the first day of school and I already hit the most devious lick."
Person 2: "Oh yeah? What'd you get?"
Person 1: *Pulls 45. out of school bag
It's called the "devious lick" challenge, which involves stealing school property and destroying or vandalizing school bathrooms, all for likes and follows. A "lick" is another word for stealing.
Dude, I just hit the most devious lick yesterday in the school bathroom.
