At least, this is the convention used in this book and by most category theorists, although it is far from universal in mathematics at large.
Either \propto or \varpropto seems to give the correct symbol. TeX often uses "var" to indicate a variation of a symbol (for example \epsilon $\epsilon$ vs \varepsilon $\varepsilon$; \theta $\theta$ vs \vartheta $\vartheta$), so "propto" seems like a reasonable guess as to what this symbol should be called.
$\\mathbb Q$ is used to represent rational numbers. $\\mathbb R$ is used to represent reals. Is there a symbol or convention that represents irrationals. Possibly $\\mathbb R - \\mathbb Q$?

There is a common thread running through many of the mysteries and hints in the series—the mysterious symbol, (alleged) astronomical symbols, cannibalism, and the sign of the bird and water symbolism in Episode 8. This thread also runs through questions with seemingly obvious answers, especially, “Why is the series called Yellowjackets?” It all boils down to trigonometry, occultations ...
I personally think that it's a symbol of his transition into a semi-delusional relationship with his "mother" (the sand). Only the sand loves him, so it wrote love, but the sand also hurts him, so it wrote love in the form of a bloody scar. Or he just wanted a cool tattoo.
