UBNL, pronounced 'Ub-Nul' stands for 'Upper Body, no legs' and is a phenomenon seen in gyms across the world. An UBNL is a person (usually a man) who has lifted weights for a considerable amount of time and developed a very muscular upper body... but the retard (for whatever reason) has neglected to train his pegs and consequently has ended up with a set of girl legs that a big pink flamingo wouldn't want to be seen standing on.
Dave: "Look at that guy over there, what an UBNL".
Hot chick #1: "Wow, look at how big his chest is!"
Hot chick #2: "Yeah but have you seen his skinny legs though? What an UBNL.
