'Yo Mama' Attack

When, in a discussion online or elsewhere (but usually online) a conversational opponent fails to argue the issue and resorts to personal attacks, calling names or expressing other, irrelevant nasty attitudes about the person.

This is exemplified by the (possibly apocryphal) phrase, "Yo Mama" to suggest that someones mother is a whore, even when neither she or whoring is under discussion.

Other examples include, "you're a communist", "asshole" and "you're a hypocrite.

Executing an unforced (ie, the opponent did not engage in it first) 'yo mama' attack results in a win for the recipient of the nasty accusation.
