What is Drunk-sitting?
1.
Looking after your drunk friends when you are the only sober one. Keeping an eye on them, escorting them everywhere, keeping them out of trouble and sometimes cleaning them up. This should also include making sure they get home safe with all the belongings they brought with them.
"Yeah, the dance was fun but I spent pretty much the whole night drunk-sitting Mary! She wouldn't stop telling people how drunk she was."
