A transit agency for the Philadelphia region. Gifted with a great system inherited from the PTC, P&W, Red Arrow, PRR and Reading Railroad, but hamstrung by a shitty management almost from their start in the 1960s. They ignore the city while pandering to the suburbs, fucking over the source of 60 or more percent of their ridership. They are simultaneously cursed and blessed by many residents of Philadelphia.

Also a killer of trolley lines, and inventor of bustitution.
Goddamn SEPTA sucks, why do we need a fucking line to Reading when we can't even run enough rail service on the routes we own!!!

SEPTA must pull random times for their schedules out of their ass; their buses or trains are always late.

It is the transportational system of Philadelphia and it's surrounding areas. It is pretty shitty and unreliable and is known for having strikes. There was also a train on the regional rail that had crashed while they were on strike. The train only ran while they were on strike because the regional rail is a different company or union than septa but is still called septa. It consists of buses, subways although there are only like 2 subway lines lol, trolleys, and regional rail. They never arrive on time and you should just go drive unless it is to the phillies world series.
When the fuck is this SEPTA gonna get here?

The last girl a guy dates before coming out of the closet.

Particularly applicable when this has happened many times to the same girl; she is the train men ride from their closet in Trenton to the out and proud parades of Philly.

A doubly unwitting beard.

A special kind of fag hag.
Don't mess around on that SEPTA, she'll be the last ride you take.

Turn them once: shame on you. Turn them twice: you are the SEPTA.

(To a gay man): Don't get your hopes up just 'cause I'm riding the SEPTA.
