Genuine, unfiltered excitement or emotion — not performed, not exaggerated, just real. From 찐 (real, genuine) + 텐션 (tension/energy, from English "tension"). When someone's hype, joy, or reaction is clearly not for show.

찐 = real, genuine (shortened and intensified from '진'짜)

텐션 = energy, hype (Korean pronunciation of "tension," used to mean vibe/energy)
