whatever drowns your goat

Oops. Your boat failed.

Tim: Whatever floats your boat
Tom: i have failed to float my boat
Tim: welp, whatever drowns your goat

drowns your goat

When you feel like being a kind of psychotic idiot and don't believe in the floating of boats, but rather the drowning of goats.

"Hey I think we should take a break."

Well, whatever drowns your goat."
