a squid or someone who acts like a squid. a motorcyclist that wears less gear than appropriate, shows off doing stunts before perfecting them, riding beyond his abilities, or just plain doing something stupid.
Did you see that new guy trying to show off in front of all the other bikers?
Yeah, he ripped out of here up on one and almost lost it in traffic. Johnny Law saw him and wrote him for exhibition of speed and being squidly.
A very weird person. You can usually find them in a cave, crawling towards you growling and making weird noises, eating anything they find on the ground, or running around like they are on crack. But all in all they are a fun person to be around and you are lucky to know one.
