foster's whirlpool

Sex act in which one takes a can of Foster's Australian lager and a beer bong inserting the hose end into the partners anal cavity and pours the can into the beer bong. The act can include a lego surf guy. Just make sure to tie a string to the surf guy, so you don't have to send the lego diver in after him.

Man, this chick let me do a Foster's whirlpool to her. Yeah. Lost the lego guy though.

foster fuck

A foster fuck is someone that is constantly used by others as a rebound. But in a way that they show the hurting person how amazing they should be treat. Like fostering an animal to find it’s forever home. Similar to the movie Good Luck Chuck.

Him: “You’re so good to me and treat me so well, but I don’t want to date you.”
Her: “ Oh I know, I’m just a foster fuck for you, until you find someone that you think is better.”
