1.) Description of a person that is either too stupid or too arrogant to wear a condom when performing sex or when about to perform the same. 2.) A really stupid convict or an ex-con, denoted for being extremely idiotic or devoid of common sense.
Sex: "If you think that I am gonna let you stick that thing in without protection, then you are a real 'condumb'! Better get reacquainted with your hand!!"
Gangs: "Boo Boo Bear got popped by the cops for something really stupid. He's a real 'condumb'!"
Prison: "Harry the Hun got parole, but he got into trouble again on the outside, so he's back. Whadda a 'condumb'!"
A clear umbrella, the likes of which makes the wielder look like they are hiding in a condom from precipitation. The more people utilizing the awkwardly domed and transparent umbrella, the more ridiculous the scene becomes.
Person 1: It's raining awful hard, why not use my umbrella? There's room for two.
Person 2: I will not add more seed to the contents of your condombrella; I'd rather chance the rain.
