A definite finishing
line in an argument. Usually crosses the
line and is a very offensive statement, but results in a decisive and unanimous win for the
person who executes it.
Jones and I were arguing for about an hour last night, til I

sister straight with my cock of glory.
"I'll dig your
mother up out of the grave and skull fuck her!"
"Damn, killshot!"
