Originated by the Penny Arcade strip "Prefanity", "Strawberry Smurf" is some perverse term involving arbitrary sexual acts, necrophilia, and gnomes. This can include any form of Gnome, whether it be from Warcraft, D&D, or just an exceptionally short person in real life.
Last night I decided to roll an alt on Moon Guard and check out what was going on in Goldshire. Some Gnome chick asked me to give her a Strawberry Smurf. I logged immediately.
When you're getting a chick from behind, pull out, and spit on her back when she turns around punch her in the face and ejackulate on her face mixing the blood and semen its called a strawberry swirl.
when your girlfriend is giving you a blow job and then just before you cum you punch her in the mouth making he bleed into a glass then you cum into that glass and it looks like a strawberry cream pie
