a fine ass, not huge, but one that you just have to grab on to. one that when a girl walks by, your eyes just automatically follow its bouncing movement, like a jumping kangaroo.
"Damn, dude, you see the ass on her? my head spun around so fastt I cracked my neck."
"Yeah, man, she got a kangaroo ass!"
"Yeah, man, she got a kangaroo ass!"
