Answer:
While I was eating my supper I found out they were planning to feed me dessert.

A squinting modifier is one of the types of misplaced modifiers; in this case, the squinting modifier makes the meaning of sentence ambiguous because it is not clear whether it modifies the previous clause or the next after the modifier. The original sentence could either mean that the person would be given dessert after eating dinner or at the same time.
