A motorcycle rider who demonstrates a lack of respect for the general public and the failure to realize the possible negative impact that could result from their riding actions on public or non-public roads.

The squid is just unable to rationalize or conceptualize the possible negative outcomes resulting from their actions. This is regardless of whether or not they wear protective gear.

The squid does not realize that it is not that they are not wearing gear that makes them a squid - it is the fact that they think they are exempt from social morales and can pull a 10 o`clock wheelie on public roads or weave in and out of traffic at twice the traffic speed just because they can.
