lose your marbles

Lose your marbles = lose one's mind, insanity, person who does not have common sense/wits.

I knew she'd eventually lose her marbles = I knew she'd eventually lose her common sense/rational mind

Have you lost your marbles?. Means the same as "Have you lost your mind"?

Ass marbles

Similar to anal beads, they are small round objects inserted into the rectum for sexual satisfaction. They are meant to be used in moderation and are guaranteed to heighten sexual climax.

Due to insufficient anal satisfaction the homo sapien used ass marbles to enhance their sexual pleasure beyond normal constraints.
