A man who is named as an uncle but is not actually related to the person. Ugly Uncles are normally a group of old friends who have grown old together and spend their days drinking beer, talking shit and giving out unsolicited advice to others. Ugly Uncles often fall asleep in their chair after too many drinks, often loose belongings such as hearing aids and have been known to pick up the wrong personal items (such as phones and wallets) when they leave a social event.
Who's that licking the floor over there? That's Phil he's one of the ugly uncles, don't take too much notice, it only encourages him to continue acting like a twat.
