Someone who is fully aware of what is going on although others around him might be confused.
"Mate, what just happened?"
"Yo dawg, a guy stole your jacket while you were buying a drink!"
"Damn! You such a Tuffley!..... I want my jacket back though."
An attractive, older woman who is marred by random, inexplicable "snorting" noises, that are very similar to those a truffle pig make when on the hunt.
Dude: did you sore with that cougar from the bar last night?
Me: nah. I spent 20 mins with her and found out she was a total truffler. I couldn't take it anymore
so bailed in search of some trim.
