Littastic is a word I said today and it’s a mix between you guessed it lit and fantastic. WOAH mind blowing stuff right there. So as you can probably guess It means it’s the best there is the best there was and the best there ever will be
The state of being filled or abundant with lint, as a dryer lint trap or one's navel. Other things could, conceivably, also attain the quality of being, literally or figuratively, "lintastic".
