A male sex partner who pretends to be deceased or very stunned during the act of lovemaking.
This can either be through the acting out of a fetish or through the partener just being very shy.
Negative example:
"OMG... he was suuuuuper hot, but a total Sex Possum... eiw"
Positive example:
"Sometimes my partner and i like playing sex possum; where i pretend to be dead.. its amazing, she loves it man."
Snow possum is a term invented by POC (people of color).
It describes caucasian Americans who hold views that can be considered racist and harmful to the black community.
Getting offended by such a term likely means that you sympathise with them.
Generally we wouldn’t use this term against non-racist caucasian individuals.
Even if it’s really funny.
Racism is no laughing matter.
Yosnow possum, what’s it like being racist? Ahahahahaha
