adj. Stands for "Tight Tight Real Tight." This is another way of describing what someone did as really awesome. It's considered the less intense version of its counterpart phrase, sicky sicky nar nar. TTRT can be used in text messaging as a simple way of reminding the recipient of the text, that what they just told you is truly worthy of a high five.
