‎'Locked On' - adjective: slang pod term used to describe moments when a person gets completely obsessed with an idea and keeps running with it until they realise that they're acting like a freak. Often includes rambling and random tangents. Generally 'locked on' period lasts no more than 5-10 minutes, but has been known to extend to the wee hours of the morning and result in some really stupid decisions (commonly combined with alcohol/alternate means of intoxication in these extremes).
Talking about someone. "Wow, they got locked on."
