A woman that uses a shewee for sexual gratification. A shewee is a portable urinary device for women of all ages which allows them to urninate standing up.
Sheweets mainly use the device to penetrate men and women during intercourse.
Jane fucked me in the ass with her shewee last night, I would never have guessed she was a sheweet!
The cartoon equivalent of a young Karen. She used to be a good character in Wreck it Ralph 1, but is now a total asshole in the sequel that does not consider the consequences of her actions (except that one scene where Ralph nearly gets her killed, until he told her why he tried to stop her from going Turbo). She ended up going Turbo at the end of Wreck it Ralph 2 anyway and got away with it, unlike anyone in the first movie.
Person 1: I hate everyone around me and I only care about myself.
Person 2: Stop acting like a Vanellope Von Shweetz.
