(1)A song written by
Tom Higgenson and sung by the Plain White T's.
Tom wrote the song for Delilah DiCrescenzo in the
summer of 2007. He did go to college with her, but they were never in a relationship. In fact, Delilah was very uncomfortable with hearing the song, so when she heard it on repeat everywhere she went, she had to think the song wasn't about her. It never worked.
(
2)A greeting. It could just be a friendly greeting like, "Hey there, Delilah!" Unless your name isn't Delilah. Then the
person you're talking to is either delusional or referencing the song.
Unfortunately, however, we will never know what it's like in NYC.
