Net hanger
Similar to cock blocking,it's what an ugly dude does when he knows he'll never score the hot chick he's standing next to or sitting next to in a bar. But he won't leave his seat or spot if his life depended on it. Therefore, preventing anyone else from getting close to her.
" I was really digging that chick sittting at the corner of the bar last night,but some net hanger wouldn't let me get in close with her."
