A qualifier used to diffuse tension at the end of a particularly serious statement. The user of this qualifier usually anticipates a negative reaction (the nature of which is either anger or awkwardness) from the listener, and thus hopes that adding the word "lol" will convey a tone of facetiousness, which is often not discernible in netspeak.
Johnson: Hey Timothy, last night I shat in your mother's vagina and farted in her mouth, after which I proceeded to masturbate on her face and urinate all over her body lol.
Timothy: Haha, oh Johnson, you never fail to amuse me.
Johnson: I wasn't kidding, lol.
Timothy: Haha, oh Johnson, you never fail to amuse me.
Johnson: I wasn't kidding, lol.

Get the lolmug. 
A term often seen in text messages, typically used when the sendee is too polite to tell the sender what they really feel about them or generally written in the absence of personality. Very contagious phrase. Lol.
message sender 1: Hey. Lol. How are you?
message sender 2: Good. Lol
message sender 1: Lol
message sender 2: Lol
message sender 2: Good. Lol
message sender 1: Lol
message sender 2: Lol

Get the LoLmug. Back when chat was invented, believe it or not, the meaning of lol was nothing more than Lamer On Line, so most elite guys would use that too alert others and make fun of lamers without their knowledge, course lamers not knowing that, did not understand the meaning and quickly it became known to be Laughting Out Loud, score one for the lamers... :) all this happened when text was king and the net a mirage...like i said...believe it or not.

Get the lolmug. the thing you say when you can't think of any other appropriate response. Sometimes used in conversation face-to-face, much to the chagrin of the English-speaking world.
