The result of white people tangling, matting, and dirtying their hair in an attempt to grow Dreadlocks.

As it is impossible for a white person to grow Locks (dreadlocks, locs, etc), this phrase becomes necessary.
Example A:

"I think I might grow some Locs..."

"You mean you might grow some Dolltails."

Example B:
"You better cut off those dirty-ass Dolltails before someone smacks you for your ignorance."
