Car sitting 

When you sit in your car doing nothing but browsing through your phone and listening to music.

My boyfriend is always car sitting

catsitting 

An often occurring event when Skidoo riders, out of charity, allow cat riders to ride with them. After a rip through the woods, the Doo riders will invariably be forced to wait for the cat riders to catch up. More often than not, the cat riders never show up due to mechanical failure of their inferior sleds. Hence, the term catsitting refers to Doo riders sitting and waiting on cat riders.

We went rippin with Arctic Cat Dave in Cherry Creek, but ended up catsitting most of the weekend.
