To be molested with the tonuge. Involves the licking of a particular part of the anatomy when one is not expecting AND not particularly wanting it; most usually the face. Tonguelestation is never violent, only done in a playful manner meant to amuse those around and to slightly (or severely) irritate the person being tonguelested. The usual consequences of tonguelestation are the victim being covered in large amounts of slobber and the tounglestor being smacked (usually in the arm and usually playfully).
I was tonguelested in the face by my fellow trumpet players at the football game.
