I don't mind spitting, I'm not talking about the just bc I don't wanna swallow my saliva, but the I have phlem in my throat and if I don't get it out I will choke...I agree that clipping nails in public is nasty (an ex of mine did it on the subway once and I flipped)...other nasty habits include: scratching yourself in public, really digging deep in there (this is even worse when a girl does it), picking ur nose (just grab a tissue and blow ur snot out), or basically picking anything (ears, eyes, hair, whateva)
