napadno

1. (of appearance) showily; garishly; flashily
   Bila je napadno našminkana za jednu kafu. — She was wearing way too much makeup for a coffee.
   On se uvek oblači napadno. — He always dresses flashily.
2. (of behaviour) conspicuously; pointedly; ostentatiously
   Napadno je gledao na sat dok sam pričala. — He kept pointedly looking at his watch while I was talking.
3. (of behaviour) intrusively; pushily
   Napadno joj se udvarao. — He courted her very pushily.

Usually disapproving: napadno means "too noticeably", while the neutral upadljivo just means "noticeably".
