(From ED) A lol-cow is a victim of a Flame War who can't help but be milked for lulz time and time again. They have a compulsive need to give up as many laughs as possible at their own expense despite themselves.

A lolcow is a person you get extensive laughs from, who doesn't know they are being made fun of. They can often think they are admired for what they are doing, but secretly are being laughed at constantly.
See that obese lady dancing on cam? She's such a lolcow.

A phenomena, usually observed on forums and/or imageboards. A person, most often someone who tries to look exceedingly knowledgeable in the topic discussed, is being flamed/trolled to the point where they can no longer present "sane" arguments that will "fit their level", but yet are too proud to just quit.

This produces a considerable amount of lolz and win, for which the said person can be "milked" until they finally give up. Or drop dead. Hence the name.

A good Flame Warrior can turn even the most dignified poster into a lol-cow, dehumanizing them every step of the way. For some unknown reason, the lol-cow cannot break the cycle and regain their humanity.
I wish I could stop checking this forum topic, but the lol cows come back time and time again to be milked.
