Foamies?!?!

I've heard some things about the foamies (?!) but wasn't exactly sure of what it was.....can anyone help me?  And if that's what I am experiencing, what can I do to stop it?   Thanks for all your help.

i have heard that foamies is when you foam at the mouth. your saliva gets thick or something. I guess when you start to get sick or if you have eaten something that does not agree with you.

Laura if it is the foamies the only thing that stops it when i get that way is to make my self throw up what ever the offending food is.  I only get it when i eat too much , too fast or dont chew something up well enough. The foamies is spit  that just come on and on and on and you cant swallow it fast enough, it just foams out like a mad dog. Sorry but that is what it reminds me of and the only thing that stops it is making myself throw up. then it is all over with. Jan
