The act of floating down a river in a canoe or raft while drinking alcoholic beverages. Usually done in large groups. No paddeling is involved unless absolutely necessary. As a practical joke, it is a common occurrance to flip over other canoes. Usually done in a shallow body of water where wading is possible due to frequent potty breaks.
Similar to frape, a profile screw is when you either:
1. know somebody's facebook password and log into their account from home, to then frape them
or
2. someone has left themselves logged onto facebook on your computer/phone and you then frape them later on
