creepy

creepy: hormigueante

creepy, according to wiktionary:

1. producing an uneasy fearful sensation, as of things crawling over one's skin
2. strangely repulsive

my friend Jonathan suggested the dictionary site Tomisimo, which came up with hormigueante. good! much better than what word reference came up with (espeluznante)
