Mannurse: Verb. To take care of your drunken man friends after they have had far to much to drink. To also make sure they don't do anything really stupid while drunk, but what's stupid or not is debatable. This can be very tiring especially when you are the only sober one out of 5.
"After the 4th of July last night my friend had work at 6 AM and was so totally hammered, so I had to mannurse him from midnight until he was sober again by letting him crash at my place and making sure he didn't break any shit."
