Buy a new very sharp cuticle scissors, sterilise it and cut it off. It doesn't hurt at all as there is no nerve there, but it will bleed tons. That's how doctors generally get them off too. Skin tags - the bane of bodybuilders - under arms and between the legs especially.
Nail Clippers worked best for me. First one is a little scary as it seems like it would hurt a lot but after that it's easy work. A dermatologist told me to save money and do it myself as they charge....(whatever it was) for something that you can do yourself in less than 5 seconds.
Cutting them off hurts less than any other method. And it's instant
Tie a price of cotton around it to cut off the blood supply. It will fall off after a few days. Just did mine this weekend.
