high octane
Full of energy
High octane literally describes fuel with a high octane rating, which resists premature ignition and allows engines to perform at higher compression.
The phrase has become a common modifier for anything intense, powerful, or action-packed: a high-octane thriller, high-octane energy.
The figurative use suggests excitement and relentless pace.
