The "Cash Me Ousside" girl says her whooping some ass on a plane Monday was totally justified ... 'cause a lady put hands on her mom.
Danielle Bregoli gave us a blow-by-blow of her fight with the passenger, saying the videos -- obtained by TMZ -- don't tell the full story, and that the "victim" of her blows actually initiated the aisle brawl by pushing Mama Bregoli ... who was in a cast.
Sounds reasonable ... but we'll let you be the judge. HowBow dah?
