Do guys have em too?
How about pretty or ugly days?
Re: Thin days/Fat days?
Yeah and in addition to these I also have good hair days, bad hair days, glowing skin days (rare), dull skin days (almost always), smelly feet days, not-so-smelly feet days...
I have good and bad hair days and I always have fat days 
Guys definately have fat days when their “tond” starts to show 
and they need to do crunches or start jogging.
Re: Thin days/Fat days?
** I've never had Thin/Fat days... I'm always active as in sports or having a spotless apartment and I hate cold drinks... always water for me! and I drink lots of it... I guess it comes down to the lifestyle you choose for yourself...**
