O'Keeffe 

An Irish surname translating from Gaelic to "kind" or "caring"

That's it. That's literally it. It has nothing to do with cumming in a man's eye, as stated by the only other definition that exists on Urban Dictionary (as of writing this).

The O'Keeffe family really are kind, aren't they (?? idk I had to do an example)

O-blamer 

An extreme right-winger who will blame President Obama for anything and everything under the sun. Obama can do no right in their eyes, even when he proposes ideas that were originally republican ideas. An O-blamer is that crazy, reclusive uncle who at family gatherings will go from a completely unrelated topic into a tirade about how Obama is a socialist who wants to take all your guns away, force everyone to gay marry, build mosques in every city, ad nauseam. While there are certainly legitimate criticisms of Obama's policies, O-blamers are known to let their imaginations run wild.

O-blamer: "I was so hoping to get a Hummer H2, but I lost my 401k when that godless-kenyan-muslim-socialist-commie-nazi-antichrist was elected, and now I'm stockpiling ammo for the revolution!"

Everyone else: (quietly observes for fear of sending the O-blamer into a violent fit of rage)
