An unusually small penis, cock, dick, tool,member, prick ect.
at times even smaller than a pensil

Usually found on rich sports car driving pretty boys and boy band members.

also used to show ignorance
I heard Roseann hooked up with that pretty boy from the american idol show and he had a pensil dick.

I dare that pensil dick, pretty boy to try and get some feel up in my ex's huge ass pussy!

Bob you fucktard, pensil dick idiot!
