Baby poseidon is the generic brand blue raspberry juice you get at your local grocery store for at MOST $1.50. This is the juice you take home in slurp down in 2 days and is 0% real juice. This type of juice is also known as blue drink or some people just call it Kool-Aid.
XBOX Live Gamer: Hold on guys, imma go grab a glass of that baby poseidon real quick.

XBOX Live Gamer 2: Alright, we'll wait for you.
