This is not a formal expression 애긔 - Maybe it would means 애기(baby)
존잘존잘 - This is not a good expression either. it means "very handsome, very handsome" or "very pretty, very pretty"
"존잘" is "존 잘" and it is "존나 잘생겼다." but the problem is that the expression "존나" is very close to "fXXXing"
That's why this expression is informal.
