A chod "slash" flange. The act of flodging is a complex self-pleasurable action.
Instructions:
1) Form a fist-like shape with the hand (as one would when....masturbating the penis)
2) Extend the smallest finger (pinky)
3) Move the hand in a sliding motion so as to masturbate the penis whilst shoving the 'pinky' up the vagine FOR DOUBLE THE AMOUNT OF PLEASURE
The edge of an opening or a cavity, specifically, the protruding metal (or sometimes wooden) structure located at the bottom edge of a door frame.
I really thought I could get my drunk ass home and in bed quietly until I, while entering my apartment, tripped over the flodge and woke up all of my roommates.
