A filthy rude person that commonly emits stench, both verbal and physical. Unlike some beliefs pusbag does NOT relate to an act of being pussy or a coward. Its a combination of words Pus - (a yellow-white fluid a due to infection) and a Bag. Calling a person pusbag gives them consistency of containing nothing but filth, disease and shit.
Jabba the Hut - he's a huge pusbag
Moe Sizlack - nothing good ever comes out from that one...
a term used when calling someone a pussy is not emphatic enough.
Richs girlfriend wouldnt let him go to the bar with us after work so he didnt go. What a pusbag!
