Single fish eye

As you're doing your female companion from behind and lick your thumb to jam it up her ass and she gives your the single eye look when she turns her head.

"Man jim, I was fucking Becky and she gave me the old single fish eye"

Singleish

I philosophy/lifestyle on love and relationships in which one remains single in the sense of not entering any kind of committed relationship but continues to date and enjoy non-platonical relationships with not intentions to start one. They do not want to simply have sex with people or they would just be a player.

They are crucially open about their desires and do not lead anyone into thinking they mean to commit more than they do.

Preston's so cute, is he single?

I've heard he's singleish.
