Whipping it out to me(and most moms I know) means pulling out the breast and exposing it, letting it remain exposed when the baby is not nursing. There's a huge difference between nursing without a cover, and what is referred to as whipping it out. A very blatant act. And I really don't care either way, just trying to clarify the term. I do not feel it's offensive, either, as I whip it out at home just around my husband and kids and mother all the time! In public I try to be careful to keep the forbidden nipple hidden(though that's pretty silly, isn't it...why should that part be more private than the whole rest of the breast that's exposed in a bikini?!)
Yeah, I don't really understand how the term "whip it out" is offensive. It's a general term usually used to describe getting something out in a quick manner, e.g., I often whip out my wallet to pay the cashier at the grocery store (emphasis on function). When I say whip it out I mean I give no thought to my surroundings and am mainly focused on quickly feeding my ds, but I don't generally leave it hanging out unless I'm at home. He does pop on and off a lot, and I spray quite dramatically (I have very heavy let downs), so I usually have to cover my nipple or I'll soak myself. That's my experience anyway.
I agree with you purplerose, it is pretty silly that the nipple is considered more taboo than the whole rest of the breast which is on display and considered acceptable in a bikini.
