General referential slang for cannabis, harvesting and transporting cannabis, the act of purchasing cannabis, the act of smoking cannabis, or even attempts to remember events after being intoxicated by cannabis.
Origin: The movie "Super High Me" contains a scene in which Doug Benson is given a small memory test- asked to remember and repeat the words "boat" "cucumber" and "wire". Later in the movie Benson comically says "Cucumber wire boat" after purchasing cannabis.
When one buries his/her face in the ass crack of another person and shakes their head back and forth while making a motor sound with their lips. Very close cousin to the Motor Boat.
Did you see her ass?? I'd TugBoat that in a heartbeat!
