Pulling weeds and tapping shoulders.

A term used in Call Of Duty to express how much you raped the other team. The outside world won't know this, so you may use it as a bragging tool in everyday situations.

1: Aww man. Just pulling weeds and tapping shoulders, all day every day. 120 kills and 29 deaths.
2: Kickass day at the beach. Just pulling weeds and tapping shoulders.
