a "nickademus" is a man retaining a wide knowledge of alcoholic beverages and is able to drink vast amounts of liquor in any social (and perhaps non-social) gatherings. A nickademus is also a bro of sorts. This man is not a shrimp, he isn't all the way there in terms of being super buff, but he does have some muscle.
"Hey dude, you see Ethan over there? Bro he is so nickademus right now, he just pounded 2 and a half 40's in half an hour!"
