A subtle, obscene gesture used when you can't find the words of hatred to use against another individual (human, animal, etc.) Generally used against authority figures, such as a supervisor, superintendent, or even a bossy in-law. Gesture is performed by sliding your hand down to your thigh area, and popping an upside down middle digit.
Feelings conveyed while using this gesture are "go f*ck a hat" "sit on it and rotate" "please wash your mouth with a 12 gauge" and "I will fill your urethra with pine cones". Ladies and gentlemen, the Lurk Finger.
