n. Half man, Half beast. We all have a friend like them. Toenails alittle hectic, beard always long and uneven. Children fear of being eaten. KEGS fear of being tapped. A kupfer can be spotted at any party where there are winebags being chugged, and chugees being hit deaf. You will always spot a Kupfer 95% of the time under a bubbling, upside-down bottle.
"Dude you went Kupfer-mode last night"
"oy! ive spotted a wild Kupfer over yonder! If you look closely, you can see a flcok of claifornia quails who have laid nest in the pajamas that kupfer has been wearing for 3 months!
