is an acronym for Love You To Pieces or Luv Ya 2 Pieces. It's what I say to my closest friends and relatives in TMs and emails. A loving sign of affection for your closest buds. As good as, if not better than, I heart U.
I've known and respected you for years, that's why I say LYTP when I sign my letters. Can you believe Todd told Ginger LYTP in that email?!?
Lytp means Love you to peices
I've gotta go, lytp xoxox
