Some serious shots were fired on Tuesday's episode of Tough Talk ... after one finalist accused her opponent of being a "ring rat" -- a word used in the wrestling community for groupie.

It all went down live on the WWE Network -- when Amanda accused Sara Lee of being a "ring rat" who spends more time with the NXT wrestlers, than on actual moves in the ring.

Sara quickly shot down the accusation ... and insisted it was only a mind trick from her fellow finalist -- but after the show Amanda backed her claims with a tweet saying, "The truth hurts ... #RingRat #SorryNotSorry."

Check out the video -- Paige's reaction is classic.
