A sexual maneuver where a man shoves his penis down a woman's throat and holds her mouth open, as she's gagging. She may try to throw up or choke, but the force of the penis and her mouth being held open results in everything going back down the way it came. At some point, ejaculation on the part of the male is expected.
Yeah, Steve had to top kill that last night. Things got out of control.

procedure used as a means of sealing an oil well that is experiencing an uncontrolled eruption of crude oil or natural gas. The process involves pumping heavyweight drilling mud into the manifolds connected to the top of the well. This procedure stops the flow of oil and gas from the well and is a prelude to sealing the well completely (usually with cement).
BP engineers had injected a "junk shot" of heavier blocking materials as part of the "top kill" procedure being attempted.

The term used when you've taken a crap and it clogs the toilet completely. Thus allowing now water down until the blockage is removed.
