Adverb of 'sketchtastic' -the combination of 'sketchy' and 'fantastic'. To move around in a sneaky way trying to stalk someone without him or her noticing, all while doing it in a fantastic manner.
Hold on a sec, I'm moving from room to room sketchtastically in order to get a picture of my ex in an awkward situation. Hope he doesn't see me.
