awavauatush

I keep seeing "AWAVAUATUSH" in binaries. Turns out it's a popular function prologue:

00000000  4157      push r15
00000002  4156      push r14
00000004  4155      push r13
00000006  4154      push r12
00000008  55        push rbp
00000009  53        push rbx
0000000A  4889FB    mov rbx,rdi

There are a bunch of similar strings that have fewer Google results, like AWAVAUATARSH and AWAVASAQAPWVQRARPA.
