One unfortunate issue for runners with big boobs — or boobs in general — is the inevitable, and sometimes painful, titty bounce that comes with every stride.

We all know it, so there's no reason to point it out... one would assume.

Except for one dumbass "nasty old man" who made it his business to inform Michelle Kirk, a runner from Florida, that running is making her boobs sag and she should get a better sports bra (because obviously somebody needs to tell her!).

Kirk's response?

A *literal* middle finger (much deserved IMO), but also a few choice words for the jackass:

To the nasty old man who stopped me mid-run to inform me that I need to get a better sports bra because my boobs are sagging and will only sag more if I continue to run... fuck you. You are the reason why women have insecurities. If you don't like the way my boobs 'sag' when I run, then don't look! I will NEVER stop doing what I love and I love myself way to much to have your hate bring me down!

Let me be the first to say: YAAAAS KWEEN! ...OK, I'm not the first — many of Kirk's friends have already sounded off in support of her reaction:
