From a mishearing of portmanteau , a "poor man's toe" is when someone mishears a word or phrase and tries to use it incorrectly in a later conversation.
Cyrus: "Guesstimate. It's a portmanteau."

Enrique: "Oh cool."

(later that night)

Enrique: "Guesstimate. It's a poor man's toe."

Alex: "Ha! You beaner."
