hdl 

A short form for the german term "Hab dich lieb" that means something like "I love you" but is rather used by female friends than lovers...
Another form is "Hdgdl" which has a stronger meaning and stands for "Hab dich ganz doll lieb".
Both abbreviations are especially used in text messages, chat conversations and in written letters.
