look up any word, like dirty sanchez:
 
1.
O/T
Used on forums to show if a thread is off topic (O/T) from the forums main theme.
This thread has nothing to do with what this forum is about noob, it's O/T.

2.
O/T
Acronym for "Orange Testicle". Mentioned on the Propellerhead forum as possible name for a new software synth. A sack of fun!
I've programmed some very organic, musky patches on my orange testicle(O/T).
