Depends on whose turn you do it on. If it's your turn, you have priority, so you can put the B ability on first. The opponent can respond by tapping it. You can pay B again to take it again, but it will still sacrifice the enchantment. It will get as many minus counters as the # of times you activated the B ability, but it will be tapped from the tap ability. The tap is in the cost, so you won't be able to attack with it unless it HAD summoning sickness.
