She was clearly worked up and in those situations (especially when drunk) we show who we truly are. Dude clearly got to her and what did she have in response?
Walk away? No.
Tell him about himself? No.
All she had was her sexuality because that's all she has become. She was losing so tried to use her sexuality (licking him) to say "I know you want to fukk me". Dude probably did, but in the moment he wasn't phased. Because he didn't react and kept going she had nothing left and so threw the water.
Dude lowkey exposed her. All that 'woofin' about being a boss bytch but at the end of the day all you got is your p*ssy. And when that goes away, you have nothing.
