Shortliner

A shortliner is a term for a group charter fishermen who have been indoctrinated into a fisheries management plan by one of the seven regional fishery management councils. Most likely against their will, with a crappy allocation and undue regulations

The halibut shortliner fleet in 3A needs an larger allocation

Shortlining

When you're talking to someone (mostly takes place in online chat conversations) and all they do is respond with the very annoying, aggravating word "Okay." Hence "shortlining." It usually happens when you're talking about something important too.

Joe: Hey how was your day?
Gary: Okay.
Joe: Well, today I went cruising with that girl I like ;)
Gary: Ok.
Joe: ... Well after I got to know her I finally confessed my feelings to her and she said she felt the same way!
Gary: Good.
Joe: ... You know what? Quit shortlining me and fuck you dude if you're not interested.

Shortline

A Coach USA bus company that provides service from throughout Upstate NY. Good service with very nice buses, except when they are so busy that they need to borrow lots of uncomfortable buses from sister Coach USA company Suburban.

Over the summer, I took the Shortline and it was really nice. I tried to take it again for Thanksgiving but ended up on an uncomfortable Suburban instead.
