look up any word, like cunt:
 
1.
A young motorcyclist who overestimates his abilities, boasts of his riding skills when in reality he has none. Squid bikes are usually decorated with chrome and various anodized bits. Rear tyres are too wide for their own good, swingarm extended. Really slow in the corners, and sudden bursts of acceleration when a straight appears. Squids wear no protection, deeming themselves invincible. This fact compounds intself with the fact that they engage in 'extreem riding'--performing wheelies and stoppies in public areas. Squids wreck alot. Derived from 'squirly kid'

A male member of the U.S. Navy and is either found in a drunken or hungover state which is dependent on the number of hours the squid has been awake. Usually found in strip/go-go bars on the 1st and 15th of each month as those are paydays. Tends to drive a Mustang, however the squid generally does not have a license due to his number of DUI convictions.
