To take your hand and to repetitively slap the inner parts of the calf muscles between ones legs. IT CANNOT BE ABOVE THE KNEES IT MUST BE BELOW. It must also be from the behind, otherwise it doesn't qualify as a true bediddle.
"Hahaha I just bediddled Sammie!"

"Gretchen, if you bediddle me again I will destroy you."

Get the Bediddle mug.
The act of tapping the interior roof of a car and yelling "bediddle" once a car with only one headlight is spotted on the road.
In one variation on the game, the last passenger (driver included) to tap the ceiling and say "bediddle" must remove one item of clothing.
In other variations, the loser must buy their fellow passengers a drink. (Not necessarily alcoholic. Just a drink.)

((Upon spotting a single-headlit car))
"BEDIDDLE!"
"BEDIDDLE!"
"BEDIDDLE"
" aaaaw man!"
{chorus} "TAKE IT OFF!"
