To peach is used when you favor someone or something

used as “to peach onto” or “to peach”

to peach is something all edgy girls use, super rare! - if you got a girl who uses “to peach” keep her. She’s been through a lot and will mean the world to you, she quite mysterious, sometimes has hazel eyes and uses way too much hair dye and into some crappy pop punk.. but trust me, she’s a keeper.

To peach means to be in much favor of something or someone.
