I like the new terms mixed with new school (fakie etc...) so you must really hate me
Jib - street mixed with grinding and railing of 'stuff'. For example to grind a stair rail would be jibbing. To simply do the gap is still urban...Esentially what bmxers have been doing for year but mtbers wanting to make it sound different.
jib(2) - sexual inuendo (sp) for something dirty
I hate the term Jib and it is like freeride no one is sure where to apply it so I apply it as the snowboarders would. Snowboarding is where it came from BTW.
