From the combination of jib as meaning one's personality and of maneuvering a bicycle.

A Jib Jib is a person whose personality is the product of others' personalities around them. These people often have no real ideas or opinions and are incredibly dull.

This is a more severe version of swag stealing.
"I was at the bar tonight and this jib jib started hitting on my girlfriend. He kept talking about electronic music and working out."

"What'd you do?"

"Nothing. When he saw me he started shaking and pissed himself."
