Metsies 

An alternative name that refers to the New York Mets, almost exclusively used by fans of the team. To be used in a loving, playful way, with hints of desperation, despair, and hopelessness.

The Metsies look to break out of their 15-game losing streak against the Braves later tonight.

A Metties 

When you just don't understand that a girl is into you.

Person 1: So dude, I was out with a friend last night, and when I was dropping her off at her house, she asked me to come in for a cup of coffee but since I hate coffee I refused her offer.
Person 2: Man, now you're just being a Metties.
