Any party thrown immediately after Thanksgiving, just before it, or... hell, maybe on the night of. A very easy excuse to get fucked up with your friends. A feast is required of either;
"hey, you guys down for a friendship-threesome?"
"just say your horny David, no one says 'friendship-threesome'."
"Andy, I know you've been bottoming the most lately but don't take that out on David."
A misspelling of friends when you are quickly trying to Friendzone someone. If you ever get a text message from someone that says (or hints at) the word “friendsa” it means she doesn’t like you man
