lift gift 

Farting in an elevator just before exiting. This is similar to crop dusting, but either leaves victims trapped with the gas, or surprises new and unsuspecting passengers.

"The guy that got off on the 3rd floor left us a lift gift. It smells of eggs and beef. Quickly, open the doors so we may find another lift! I can taste it!"

Lift Gift 

Releasing a stenchy fart into a lift or elevator, then leaving so the next person who enters can receive and enjoy the full guffy experience.

Upon seeing a work colleague leave a lift: "Let it clear. Jeff always leaves a Lift Gift in there."
