(adjective) /bas-tay-shus/
A slang term describing behavior that is shamelessly bold, overly forward, or excessively "thirsty" (desperate for attention or sexual interest), especially in online messaging like DMs. It combines elements of "bad" (in the sense of
inappropriate or cringeworthy), "nasty" (sexually explicit or crude), and "audacious" (daring without shame or self-awareness). The word captures a specific modern internet
phenomenon: sending unfiltered, overly sexual, or boundary-pushing messages to someone who hasn't invited that level of
familiarity. It's often used humorously or critically to call out lack of chill, respect, or reading the room in digital flirting or interactions. Similar to "thirsty," "out of pocket," or "down bad," but with a stronger emphasis on brazen audacity and zero shame.
