until the cows come home 

A long time, usually defining how late
someone might stay up at night or out at bars, nightclubs, discos etc.

The origin of the phrase goes back to
a time when people were familiar with the time cows came home
(in the very early morning... 4 - 5 a.m.) because they wanted to be milked.

Person 1: We are going to go out to night!

Person 2: Really? how long?

Person 1: We are staying out until the cows come home!
