Similar to the slang Wonk which in its use, in this specific case, would be similar to saying something isnt right.
"The wood was warped and wonky"
"The deal seemed kinda wonky"
Now take that an evolve it even more to be an even stranger word and you get Qwonk. Its meaning is the same yet this version will not be confused with the various other definitions of wonk.
"The wood had holes and was very warped and qwonky"
"Wow that was weird"
"yeah, it was quite qwonky"
or simply just itself...
