Spawn Kill or Double Kill

Listen up, buttercup. This joke is dark as heck. It's saying that killing a pregnant woman in a video game might count as either a "spawn kill" (killing someone right after they reappear) or a "double kill" (killing two characters at once). It's funny 'cause you wouldn't expect killing someone to be funny... especially pregnant women! You would probably cry if this was your mom. I am a bear that is based.
