Alcoholbootycall

When friends don't invite you out for the evening to party with them but say 'let's meet up after for a night cap".

Or
When your friends aren't done getting lit and call you to join them at 3 am.

Or

When you are partying with lame people who pass out early. You call your "party friends" who you know will be up for an alcoholbootycall.

Alcoholbootycall.

"Did you go out with Susie and Ricky last night?"
"No, we weren't invited. They did text us after the bar closed for an alchoholbootycall tho"
