When a straight woman is enticed into loving a member of the same sex. Usually through some wild experience or situation.
Angelina Jolie apparently causes the lesbianing of many women. Another is Sienna Guillory. In her breakout role as Jill Valentine in Resident Evil: Apocalypse (2004), she effectively turned a good amount of the straight female population into lesbians.
Can be used to describe homosexual men becoming straight too. The reason why there is no "gaying" or "heterosexualing" is because this phenomenon has mainly occured among women. This is why lesbianing has its cross-use applied to homosexual men becoming male.

Slang for an emergency T-type spare-wheel for a vehicle. These types of spare wheels are not very wide. Usually a torus-like tire affixed to a steel rim. They vaguely resemble the delicacy of the same name.
Not to be confused with a spare, stock wheel. (As normally seen on Jeeps and large SUV type vehicles.) Stock Spares are frequently attached to the rear door (on an SUV). Donuts are a feature of some cars, and are store in a small space in the trunk.
Donuts are very limited in their ruggedness. You can't go above fifty, and can't go over bumps or anything interesting on the road.
"I tore the balancer of my alloy rim, now i'm stuck on the donut for a week until the replacement wheel comes."
