Bubbly? Ive heard of that in relation with a personality trait, but bubbly being how fat people describe themselves?
I thought that was voluptuous, curvascious, full-figured, extra cushions, fluffy, hunky, chubby, a few extra pounds...
As for gapped teeth? Meh, so long as it isnt huge (as Ive got a wee bit of a gap myself, but it used to be worse) and utterly distracting (like hers is in the London Look eyeliner commercials).
