What is" sucking teeth"? what is that "tchwipe or tchuipe" you talk about? Is it a cuss word?

'Tchuipe or tchwipe' - is "sucking teeth". It's a noise you make by clenching your teeth together and then using your tongue to pull air within your mouth.

It is the equivalent of giving someone the cold shoulder, or rolling your eyes at someone. It is a gesture (an acquired behavior) people make to show disdain, contempt, indifference, frustration, or annoyance.

Most people from the caribbean do it.  It is not a cuss word.  I guess you could say that some people suck there teeth at you instead of cussing at you.
