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.
