It means any femme/fem/female who can't keep it in her pants/skirts and looses it when she sees any guy and doesn't care whether she has character, morality and most-important, loyalty and fidelity towards any
single Man ever. Loose cunt means very loose and not-at-all strong charactered
girl or female who cannot adjust with
single Boy/Man partner ever and just fools around looking for other Guys(whenever she finds slight problems to deal with and solve it or adjust with in her seemingly
short love-life) to cheat on her Live-in partner / Boyfriend / Husband. IT'
S DEFINITELY NOT A COMPLIMENT AT ALL, BUT A STRONG OPINIONATED SUGGESTION(OFCOURSE IN GOOD FAITH) TO MEND YOUR WAYS FOR GOOD, BECAUSE NO ONE LIKES OR CARES ABOUT A LOOSE CUNT, THESE KINDA
PEOPLE (FEMALE OR MALE) EVENTUALLY ARE LEFT ALONE AND DISCARDED BY EVERYONE.
