a possible tattoo?

never been tempted to get a tattoo based on an image, but this one is pretty darn awesome.

I found it on a receipt I came across while doing FOI research for work. 

I think I'd put this word under the image: "Grrr"
for this reason:
Grrr /ˈɡɜrːː/^[1] is an onomatopoeic word which imitates the growling sound of predatory animals, and is often used with other related meanings. It is one of the rare pronounceable words of the English language that consists solely of consonants.
