Seastar
A beloved term used in place of the word sister. Typically used by someone who loves the ocean and finds this word to be more fun to say.
"My seastar hates fish, but I love them."
Dead Seastar
Sexual position when someone is so tired that they just lie on their back with their arms and legs spread wide and wait for their partner to go to work.
Last night when I went to bed with my partner, I was so tired that fell into the dead seastar position, and still busted a fatty.
