A half hard, half soft boner. Usually brought on by too much alcohol/drugs. Can be counteracted with half to a full 80 mg. tab of Viagra, depending on how much alcohol/drugs you have consumed.
Dude 1: Hey man that chick totally wants you, are you gonna take her home?
Dude 2: Don't think so man, all i could give her is a nermel.
A Nemmers is someone who is completely fuckin oblivious to mostly everything, is crazy for some booty, and is generally confused, but is fun to be around. Nemmers enjoy the simple life, and enjoy a good blunt from now and then to "Take the edge off", but they most likely have no edge at all.
"Bro..that guy. I think his last name is Nemmers? Anyways, totally oblivious. Almost got hit by a car this morning. Let me hit his juul though so thats cool."
"Nice"
