Drunquaintance

A person you met while intoxicated who is not necessarily a friend but someone who you've met at prior parties.
Also, remembering the person's name is not required.

"How do you know Kenny?"
"Oh that's his name. Some party. He's a drunquaintance."

Drunquaintances

When you two people are only friends when they are absolutely wasted.

Did you hear Josh and Rebecca hooked up? They've never spoken before.

No idiot. They're drunquaintances.
