Someone who is mad (as in "hella", "a lot", "extremely", and "wicked") + Irish.
This person may like to wear nothing but an apron while cooking (which they enjoy), and is out of touch with popular culture. Generally pleasant and open-minded.
I was talking a guy (with Irish ancestry) about TV the other day and he knew nothing about it. He did want to discuss food though, so he is most likely madirish.
Nickname given to bales of marijuana thrown overboard or out of airplanes. Origin is reportedly from members of the US Coast Guard in the area of Southern Florida.
