Tons Of Laughs. Much more than LOL. It's mostly used in IM, but it can also be used in a regular conversation as an interjection, if something is too good to be laughed at.
A TRR out LOUD (TOL) is when somebody falsely describes themself. TOL's are extraordinarily common on the internet and has probably been used by You, the person reading this definition, on countless occasions. The people that TOL the most are often reffered to as in "denial" or "compulsive liars".
TRR originates from the middle east. It is said to imitate the sound of a fart being released from the human body. It is equal to the western "pff" or the more common "bullshit".
TOL: Massimo - I am a hot Italian. REALITY: Mustafa - I'm a fat, ugly asian.
TOL: Jesus - I'm currently in my gap year. REALITY: HE HAS BEEN SAYING THAT FOR 4 YEARS!!
