buddy i waited a lot that some one would reply to this post but no one did. Actually today on, i am after some dancing monkeys here who are purely useless but behave like their father owns this forum. I was waiting that any of them would reply and i would bang him right here. But anyways, here is what you asked
it's really simple
disqualifier
anything that disqualifies you as a romantic interest.
Tease
anything that makes fun of the girl without insulting her. If done right, it makes the girl laugh.
Ok still hard to mix them up? Ok here is an example
you, "why are you wearing so high heels? You think you are short? I don't really like short (disqualified) but with that much high heels, i hope you would be hijaking plans off the sky some day

(teased)"
