That's not what I call it, but fine, give it a name you want even when that sounds like a charity musicfestival collecting money for Africa.
Damn. Sounds like a migraine. Not fun.
Band-Aids are what we loosely call bandages here in the US, named after a leading brand: http://en.wikipedia.org/wiki/Band-Aid
...Why anyone would name a bandage after something that is used to make a wall or molds of something is beyond me.
