On a woman a set of two or four abs looks **** and feminine without looking manly and over vain. A man looks cool and **** with with a 4 pack, while a really ripped set of six or even the full eight signifies - if not for sporting reasons - a severe level of vanity and "look at me!" Six packs fully sculpted look too overdone unless there's a slight bit of skin and fat over the top. It's like looking at a naked woman (six pack) and then looking at the same naked woman but with a neglige or swimming bakini on ( two or four pack).
cus then ur not like super ripped and creepy, but you can still tell the person has muscle and works out and cares about their body, but not excessively
