Slot is indeed from Shadowrun. It's amusing definition in the slang dictionary in the most recent core rulebook is:
"slot n. (vulgar) Mild curse word referring to female genitalia. v. To insert a chip or credstick into chip or credstick reading device." (SR5, pg. 14)(Yes, that was copy/pasted. I'm not re-typing all that.)
Geek is what SR uses for kill; Frag and its various derivatives is used where the F-bomb would be dropped normally.
