Bum-Brella looks like an inverted bum, because it has a double dome with a crease running down the centre on both sides. If you imagine two umbrellas merged together, but with a single common shaft, you'll be close to the appearance of the idea.

It's advantages are in its increased strength as the supporting shaft divides towards the top, each shaft featuring its own set of supporting struts that fan out to the left and right, with a shorter common set running front to back across the middle to pull in the crease and create a dynamic tension. Rain water will naturally run down the center towards the specific opposing points at the front and back, so the waterproofing is doubled along the crease.

It's biggest advantage is that it's very strong and looks cool. (well at least amusing in a juvenile way - bum ha ha) It's disadvantage is in the complexity of the non standard mechanism of the different folding struts. (but this is the halfbakery)

Rude people might select the flesh coloured option for their choice of rain defence.

Pathetic, infantile and offensive.

Like a sound chip that plays "Je m'appelle Emmanuel Macron, et je suis la voix et le visage de la france" but in the style of Le Petomane .. ?

That would be perfect.
