Welcome to the Greenlandic forum! I am only a learner myself, but I think your sentence means something like "eyes don't lie". Isi means "eye" and salluvoq "lie" and the construction -neq ajorpoq means you don't usually do something. It's the negative of the -sar-/-tar- suffix which means you usually do something. Ajorput is just the plural of ajorpoq because isit is also plural.
