Anagram for "Taking the Internet Too Seriously." Can be used in a number of situation where someone takes unnecessary offense at something online, especially when debating in forums.
"Dude, my friend got really pissed off at you for that online debate yesterday."
"Seriously? She's got a bad case of TITS, man."
(interj.) An alternative to 'excuse me', used after belching or farting.
This usage came about due to 'tits' being more enjoyable to say than 'excuse me' or 'pardon me', and has since come into common use in the Eastern Suburbs of Melbourne, Australia.
Person One (after farting): 'Tits!'
PersonTwo: 'You're excused.'
