Little cups of wobbly pop that are sold for insanely low prices at bars on select evenings. Ninja beers sneak up behind you very quietly until BYAHHHHHH....they knock you out cold.

Get the Ninja Beers mug.
A beer you grab when you get home after being out with friends. You quickly take a sip to mask the the booze smell coming out of your pores. Your spouse assumes it's your first one since you just got home and isn't immediately pissed for you being shitfaced drunk.
When I get home the first thing I'm going to do is grab a Ninja Beer from the garage fridge, that way my wife won't know I've been at happy hour for the last 4 hours.

A beer that is high in alcohol content, but tastes like a regular beer.
Drunk ass: Yo I thought this was regular piss beer, but this shit snuck up on me like a ninja. I was shit faced before i knew what happened.

Bro: yeah, who gave you that ninja beer?
