When a bitch goes down a waterslide and steps out and her swimsuit has ridden all up in her twat or "trim"....creating a scenario by which all the guys around can see her "junk" hanging on each side of the suit, that type of swimsuit display is called a "TRIMSUIT".
That bitch just slid down the Monster Drop Waterslide and when she came out of the pool at the bottom, she was wearin a damn TRIMSUIT!!!
