A BBW who is particularly large, more so than a regular BBW. Depending on who you ask, a SSBBW is one who weighs 250 pounds plus, or is more than an XXL.
A woman who usually weighs over 350lb, found particularly attractive by FAs. Most SSBBW are very hot.
GF: Guess what? I now weigh over 500lb. Yay!
Me: Wow. You've become one hot SSBBW
Many of these women can be lovely and decent. They can cause happiness in those whom choose to be around them. They've often endured more rejection than folks around them and have consequently needed to do more tough introspection to validate themselves and have gathered valuable wisdom and kindness in the process.
It should be noted, however, that this rather desperate self-validation, in the practice of an irrational woman, can lead to the development of a personality that is strongly disagreeable to folks who value sanity, groundedness, or peace of mind in their associates.
Below is a potential conversation that an SSBBW might incur on an occasion separate of her involvement:
Male B) yeah. I've been curious about that.
Male A) Yeah well she's an "SSBBW" and I didn't really want to bother going over the details with you of our trying to achieve platonic symbiosis despite her S.S.ness.
Male B) Oh, ok. That's cool. Anyway, why are you bringing it up now?
Male A) Well I wanted to let you in on an interesting and fun factoid: She asked me how I felt about her body.
Male B) Haha. Uhoh! And you were honest?
Male A) Yeah. I told her that I just try not to think about it. Then she pressed for more specifics on what my feelings are about fat people and my feelings about having sex with her. And I answered her, and she hasn't responded to my outreach in quite some time; I think she's gone as a result of this.
Male B)*warm smile + smirk* Wow...What did you say about the feelings about sex?
Male A) Well I told her that fatness seems to indicate strong potentials for a few things to me: stress-coping dysfunction, a lack of nutritional intelligence, poor self discipline, and poor emotional vitality. And I told her I could be wrong, but it's just what I've gathered and seen over my lifetime, and that I would find it disturbing to be bonding with a body which indicates things like that. What I didn't tell her is that her behavior fit my stereotype pretty strongly.
