literally translated:
Verukkelijk: Delicious or Gorgeous
Schepsel: Creature
Schepseltje: Little creature
I assume it's a compliment to a person someone likes, in that case it means: "Gorgeous girl/boy".
'schepseltje' isn't used much. Not so far i've heard haha. The "tje" part is a diminutive, mostly used because it sounds cute.
