いやらしい has two main senses: generally unpleasant/nasty behavior, and sexually suggestive or vulgar behavior. The sexual connotation is very common, so use with caution.

WRITING:
Usually written in hiragana. Also written as (いや)らしい.

COMMON COLLOCATIONS:

  • いやらしい(): lewd eyes, suggestive gaze
  • いやらしい()(かた): nasty way of speaking
  • いやらしい(わら)(かた): unpleasant/creepy laugh
  • いやらしい冗談(じょうだん): dirty joke

NUANCE:
When describing a person's gaze or behavior, the sexual connotation (sense 2) is often the default interpretation. When describing speech or manner, sense 1 (unpleasant, underhanded) may apply.
