Everybody Talks Lyrics

Lyric discussion by michael14 

Cover art for Everybody Talks lyrics by Neon Trees

My interpretation is that he likes this girl and is after her. She seems to like him too. But when things start to go beyond kissing she backtracks. I believe in this case the use of "Mama" means the girl he is kissing not someone's actual mother. Her excuse is that everybody talks and that's why she doesn't want to go further. "I'm a sorry sucker and this happens all the time" means he has heard this one before. Its not clear to me whether he believes her or not. Is she saying, "Everybody talks" to get out of going further? Or is he saying "everybody talks" meaning he agrees with her but who cares? Who is saying "everybody talks"? Depending on who is saying that would help me figure out more of the song.
