。！？
Stop your whining. Are you doing it or not?!
Literal
Nag-nag noisy [よ]. Do [question-か] don't-do [question-か]!?
つべこべ is a mimetic/onomatopoeic adverb for nagging, griping, or making excuses, almost always paired with うるさい or 言う. The fixed question pattern '~のか~ないのか' ('is it X or not X?') demands a committed answer, often impatiently. Dropped copulas, direct imperative tone — a blunt masculine confrontation. Each のか combines explanatory の with interrogative か for demanding emphasis.
