I Love Cards Against Humanity

I've only played this at couples parties and have never really understood it. I know you have to answer the black card with your best white one but maybe now that alcohol isn't involved you wouldn't mind explaining the game to me please. I will try to think of some things but my mind went blank because sO realized I don't understand the game.

Like if u put a sentence like
I went to the park and played with my ______
And answers can be literally anything
Like a celebrity name or something dirty or just weird

Cool, let me think about it. Sounds like a fun game to play on here and just let people feel in the blank with their own word.

Please excuse my typos
