Honestly, I've thought about it like everyone else. But then I realized it's essentially a permanent normie branding and thought otherwise. Even with that aside, I'd still have a extremely difficult time ascertaining which tattoo to get and where. This would simply be a herculean task in both the time and effort. I'd probably get non-permeant tattoos of something first and probably end up repeating the process a gorillion times.
However, I do think the idea of permanently branding your self with something you like isn't all that bad. But what is the point if you're a socially ostracized incel? Usually normies get tattoos not for themselves but for social validation and for conversation starters.
