Is spit it out based on a Board game?

"Spit It Out" is not based on a board game. It's a popular drinking game, though there are some board games that may have similar mechanics, such as:

* Cards Against Humanity: This game involves players trying to create the funniest or most inappropriate sentences by pairing cards with prompts.

* Apples to Apples: Similar to Cards Against Humanity, players try to match cards to prompts, but with a slightly more family-friendly approach.

* Codenames: In this game, players try to guess words that are connected to their teammates' code names.

While these board games may have some elements that resemble the "Spit It Out" game, they are not the source of the game itself.
