You boys have it all wrong.
From what I gather, didn't read the entire thread, it got to be a bore, but chubby chick likes you. She made hot chick swear not to tell you such. Hot chick was demonstrating to chubby chick how she should be to get your attention but she did not tell chubby chick this was her intention. Hot chick is also an attention *****. (Typical dynamic in hot chick/chubby chick relationships.) Chubby chick, being chubby felt inadequate and got wizzed at hot chick because she was stealing her thunder.
The conversation aft when something like this:
Chubby chick: He's my guy
Hot chick: He's not interested.
Chubby chick: Sure he's not aft you mauled his package.
Hot chick: If you want a package of your own, you'll have to learn to be an attention ***** like myself.
Chubby chick: Let's go to Wendy's for a frosty.
Or not ...
