Popeyeing of the forearm

a condition usually found in single men who spend so much time 'pleasing themselves in the Boy area' that their right arm over develops severely, like one of Popeye's arms...or a fiddler Crab

man: Doc, you got to help me, I can't get my shirt sleeve over my arm its so swollen.
Doc: I'm afraid young man that you have developed "Popeyeing of the forearm"
man:is it curable?
Doc: try not to wank your nutsack flat every night and shag someone instead, that'll sort it.
