a hug in which the hug-er (one initiating the hug) is grotesquely unattractive, so the hug-ee (the one recieving the hug) tries to stay as far away as possible while still making some kind of body contact
usually lasts no more than a second
guy 1: "Look at Helga trying to give poor Brandon a hug."
guy 2: "Yea! He's totally giving her the ug-hug."
