look up any word, like space monkey:

1 definition by loud,drunk,&proud to be irish

 
1.
it is the curse in which some irish men often suffer after a night of good drinking, their inability to get an erection due to them being very intoxicated
in early howard stern days, he said he suffers from the irish curse, and he was referring to his penis looking small after nights of drinking because he was unable to get an erection, pay attention to what he actually is refering to.

also, colin farrel explains in a tv interview that after a night of excessive drinking he suffered from the irish curse when he took a girl home, he obviously didnt mean that he has a small penis. also, he was born and raised in ireland, so i think he would know about the history of this kind of things.
