Going commano (or to go commando) is the practice of not wearing underwear under one's outer clothing. The phrase and phenomenon is often used in a declaratory way ("I'm goin' commando!"), particularly by women to covertly create a frisson of sexual excitement or amusement amongst friends, sexual partners, future sexual partners, etc. Modern Western social mores generally recognise "going commando" as a "playful" behavior (akin to a mild form of exhibitionism).
