full Tonya Harding
A full Tonya Harding is when a woman commits a rather extreme act of violence against another woman out of jealousy or envy. This recalls Harding's attack against Nancy Kerrigan at the 1994 U.S. Figure Skating Championship.
Ashley was jealous of Bridget when Bridget hooked up with Ashley's crush, Mark. Ashley went full Tonya Harding on Bridget because of that.
