The state of a man's genitalia after a prolonged bout of wanking, frottage or lube free sex (possibly with a post-menopausal MILF)
Derived from the state of a baggage handlers forarm after being repeatedly thrust through partially opened zips to steal cartier watches, mobiles and anything else they can get their theiving hands on.
I was up all night bumming your mum and now my cock's like a baggage handlers forearm.
