A term used when two lesbians fall in love immediately and move in together right away, often moving across states/countries to do so. It usually ends in disaster. A Uhaul is often used in the process of moving in, and then out, and often in with someone else. The "love" is usually based on superficial/shallow ideals instead of being a real relationship.
"Jane and Mary are already having problems. They only knew each other 3 months before they uhauled."
