look up any word, like bae:
putting the full length of ones tongue into any desired object or body region.
Jon: "i feel bad. last night i finally kissed Sarah."
Terryn: "whats wrong with that?"
Jon: " i went tongue-deep on her."
terryn: "oh man, i know how that feels. i went tongue-deep on some ice cream the other day."
