The best equestrian discipline. Everyone who rides horses does dressage to some degree, even if they refuse to admit it.
Essentially is like ballet on horseback. (but much cooler)
A: Heyyyy isn't dressage cool? *Dance horse, dance!*
B: No, not really.
1) Someone who tries to mow you down with thier horse in the warm up ring.
2) Someone who has more bling on thier tack than is absolutely necessary.
A: Man, her browband was glittering so much it spooked that horse and caused a pile-up!
B: Yeah. She's a total DQ. (Dressage Queen)
