A young or insignificant person; in Scottish dialect, a brat or annoying child.
From Scottish/Northern English 'git' (a foolish person) + diminutive suffix '-ling'. Related to Old English words for bastards or low-born individuals.
Gytling is basically how Scottish people affectionately insult annoying kids—adding '-ling' to make it sound both insulting and somehow endearing at the same time!
