1. Tatar (Гайдар) "bagpiper" or "shepherd"

2. Form of Haidar (lion)

3.  Gaydar (a portmanteau of gay and radar) is a colloquialism referring to the intuitive ability of a person to assess others' sexual orientations as homosexual, bisexual, or heterosexual. Gaydar relies almost exclusively on non-verbal clues and LGBT stereotypes. These include (but are not limited to) the sensitivity to social behaviors and mannerisms; for instance, acknowledging flamboyant mannerisms, overtly rejecting traditional gender roles, a person's occupation and grooming habits.

The detection of sexual orientation by outward appearance or behavior is frequently challenged by situations with gay men who do not act in a stereotypically "gay" fashion, or with metrosexual men (regardless of sexuality) who exhibit a lifestyle, spending habits, and concern for personal appearance supposedly close to the stereotype of fashionable urban gay men
