I think we need a thread to brag about our accomplishments with respect to shapes.
I’ll make a start and proudly present: the hammer
Not only can it crush the opponent on both sides, it also comes with the advantage that it is easy to handle even for kyu players because it has a handle!
It’s a screenshot from an ongoing game, so feel free to comment about the form, but please no comments about the game.
I find it useful to think of this shape as separate (but ofc derived from) the tiger’s mouth, because it’s quite a common structure that occurs naturally following good play in many contact positions (not surrounded by empty space, obviously).
I call it the crocodile’s mouth Crocodiles Mouth at Sensei's Library
I’ve toyed with naming a jug shape when there’s an extra black stone at 2-4, and a vase when there’s instead an extra one at 5-4 (making a sort of enhanced bamboo joint).
Oh hey I got a hammer in this game to… smaller hammer I guess so probably more like a mallet :-).
And this would be… a bug because it looks like a bug probably a butterfly…
I misplayed a press joseki in my last game and ended up with this “fang” shape in the corner:
Might also be a key. 
Think positive!
I will call this the “telephone pole”, it was the result of an attempt to reduce my opponent’s area (context: Play Go at online-go.com! | OGS). Use it to call for help?
A close game. White got the edge, but Black was able to dominate the middle. Final score: Black by 2.5
This should be in the meme post 
Heh something tells me that’s not a rooster…
A pokémon?
But the double ataris around P5 are open!

And, a very special one, the two anchors, also from a 9 stones handicap game:
Very wise. A truly anchored game definitely needs 2 of them.
I built a Super B2 Bomber
Perhaps, a little Schwarzwald 
LoL! 
Well, yes, it’s definitely schwarz (black), so you must be right.
(Fun fact: Even though I’m German, I’ve never been to the Schwarzwald region.)
Isn’t the tip missing? And the opponent has already spotted that weakness and played there. The two neighboring double tip stones of your bomber are nearly disconnected. The entire stability of it hinges on that single central stone, no redundancy to cope with failures at all. This is not how aircraft are built. I think you can do better next time.
Oh come on… no one likes a pedant
The bat signal almost in that one!
