The Seattle Times: Politics: Senator says he’s sorry for “macaca” comment
Shows what I know.
I (1) would never call someone “macaca,” but (2) never knew “macaca” was a slur-ish word. Shows what I know.
During the couple years or so we lived in Belém, the maid or cook would sometimes refer to one or more of us kids as “doido macaca.”
“Doido macaca” == “crazy monkey” and that we were, that we were, sometimes, on occasion.
