The act of engaging in standing doggystyle sex with a female out on a balcony, and when she is about to experience sexual climax, you pull out quickly, yell "This is Sparta!!!!" and when she turns around to ask WTF, you Leonidas-kick her in the mid-sternum, sending her over the balcony ledge and down to her doom.

The act of a glorious post-kill tea-bag preformed in any of the halo game where both members are Spartans.
After sniping KillaJeezuz with a brilliant bounce-headshot, i seeked out his body and had causal Spartan Sex with it.
