From the Süddeutsche Zeitung: Cycling causes impotence:
„There is no longer any question that cycling can cause erectile dysfunction“, comments reproductive medicine specialist Steven Schrader. „The only question now is what we can do about it.“
So if I call the next cyclist who wants to run me over on the pedestrian crossing an impotent bastard, that is by no means an insult, but a pure statement of fact!
(and no, I hardly ever use my computer for gaming, in case anyone feels the need to point that out)
