"In a minute," meaning any indefinite period of time. I don't remember hearing this till the last couple years or so, but it really grates on my nerves. As in:
"Yeah, we went to school together, but I haven't seen her in a minute."
I hear it all the time, and I want to shake every person who says it. Stop it.
Also, "baby daddy." Even worse when compounded, as in "My baby daddy daddy a police," or "My baby daddy mama made this for me."
One of my students was talking about a girl she was planning to fight.
"Who are you talking about?" I asked.
She glared. "My baby daddy baby mama."
