sorry, this definition has been delayed due to signal malfunctions and a sick passenger at 125th street.

but in all seriousness, the MTA is the transportation society of new York, and it is almost always delayed.
the entire MTA was delayed 11 times this week due to a sick passenger at 125th street, and 50 times due to a signal malfunction.

Many Trains Absent, which is what the acronym MTA (New York) will stand for once they make their service cuts and raise the fare from $2 to $2.50 on buses and subways and from $5 to $7.50 on express buses in June 2009.

Motherfucking Transit Authority, the messed up, always causing delays New York City subway system.
Most of the times, my train is either late or stopped for eternity at one stop. MTA should stand for Mothrfucking Transit Authority.
