bass jumping 

When a bass player is coveted by several bands, and therefore plays in different shows with different bands with totally different styles of music every night of the week.

Band Leader: Dave, can you come play for my band this Friday?
Dave: Shuu, I'm bass jumping a lot this week anyway.

basejumping 

BASE jumping, also sometimes written as base jumping or basejumping, is an activity that employs a parachute (or a wingsuit and parachute) to jump from fixed objects, with the parachute unopened at the time of the jump. "BASE" is an acronym that stands for the four categories of fixed objects from which one can jump:

* Building
* Antenna
* Span
* Earth

If your parachute is open when you jump, it's not basejumping - that's paragliding.

basejumping 

The act of throwing each leg over the corresponding wall of a public restroom stall and defecating. This is a variation on the always popular Spidey Dump or Monkey Dump, but a higher elevation is reached.

Dude, I went to church on Sunday and totally was basejumping during Communion.
