Sus is the gamer-rooted shortening of suspicious, popularised by Among Us in 2020 and now general internet vocabulary. The shortened form carries a lighter, more humorous edge — 'sus' is playful; 'suspicious' sounds like a police report.

Suspicious; giving off the feeling something isn't right. "He's acting sus" = something's off. Can target a person, a story, or a plan. Lives somewhere between vague paranoia and actual evidence — usually the vibe tells you before the facts do.
“"He's been acting sus since his phone started blowing up at 2 AM."”
Casual accusations, jokes about someone's behaviour, anything with a wink to it.
Formal contexts, writing about actual security concerns, news headlines.
