Worthless site. Does not have half the slang my 13 yr old mentee uses. I think I have "trifling"** and "pimpin" figured out but I'm not entirely clear what "chickenhead" means except that it is not a compliment.
Speaking of Finns and drinking, there is an ethnic slur I haven't heard much outside of Northern Minnesota: stump jumping Finn. They have a variety of Czech, Slav, Serb and Croat slurs too but the Finn one is the only one picturesque enough to stick with me.
