When a male ejaculates into a female (while she is on her period) and it oozes out like a Strawberry Thick shake. The blood clots make it out as little cuts of Strawberries.
Guy 1: Hey did you have a strawberry thick shake the other night?
Guy 2: Its not the one that you drink if you know what I mean? (wink)
Guy 1: Ah it must've been THAT strawberry thickshake.
