Do girls intentionally "show off" their butt (ie standing up for everyone to see it) when they see a hot guy?

My question is probably extremely vague. It is rather difficult to iterate and convey such a broad question within such strict character limitations/parameters. I will elaborate here.

Do girls WANT guys to look at their butts when they are walking (ie strutting)? Like do they consider it a turn-on? Often times I see girls turning around when they are walking to look at me. I'm uncertain whether it is to 'check' to see if I am looking at their butt or to just look at me.

A lot of times I see a girl I know who is attracted to me what stands up turned around from me bending over and what not. I am just wondering if this is generally used as a way to 'show' they guy what they have or whatever.
