mad beers - the amount of beer you need to drink before you're too drunk

the amount of beer you need to drink before you're too drunk to remember your own face.

I had 6 mad beers and tried to kiss the bartender.

After 4 mad beers, I cried and told my dad I was a failure.

I drank 10 mad beers and tried to ride the bar stool like it was a horse.
