Giving a hint to someone. Telling some you're going to do something without telling them you're going to do it!

sly

A canadian, beer drinking, panty sniffing, moose fucker of a friend.

Sure! Here’s a wild and ridiculous example sentence for the Urban Dictionary entry for "sly":

Filthy: "Why does it smell like Molson and shame in here?"
Wof: "Sly was here with your sisters panties. He said he was ‘paying tribute to the great Canadian wilderness.’"
Filthy: *sighs* “Goddammit, Sly. You absolute moose-fucker.”
