A mashing of the words Tickled and Giggly. Usually caused by the SWOOTEST girl in the entire world. The mere thought of causes your body to feel completely excellent. Unexplainable-- the best.
Probably caused by a girl with the first name of Elissa. Who, by definition, is amazing.
"Dude I just got done talking to my Eshe and she made me feel SOOO TIGGLY. She's amazing."
