I’m waiting for an official FReeper explanation of the term myself.

Does it mean gone “violently irrational”?

I don’t think Tiger knows what “going ghetto” means either

It means she flipped out. Do you remember those old Eddie Murphy comedy routines from the '80s? Especially the one about "Don't ever hit a black woman, she'll go crazy on your ass." And then went on to impersonate a black woman flipping out? That was before PC etiquette came along and you weren't allowed to say those things.

Of course, if Tiger had said his wife had "Gone Viking on him," that would be perfectly acceptable. And just as true. The first thing my father said when he heard this story was, "Don't ever piss off a Scandinavian woman." He would know, I guess... he was based in Iceland and dated quite a few Scandinavians... and my mom is Danish. Although I don't think she's ever chased him down the driveway with a golf club.
