ILYSMUDEK

I Love You So Much You (U) Don't Even Know. Usually used via texting while expressing gratitude towards someone, or while texting your boyfriend/girlfriend. More than ILY, but not as much as a full-fledged "I love you," which is more romantic and less grateful. This term is also often used between friends.

JACKIE: Hi June, I sent you those textbook pages you wanted.
JUNE: OMG thank you SO MUCH!!! ILYSMUDEK!
