Well I guarantee you no one would know it unless they specifically played Undertale. But that could honestly be said for any Undertale shirt that doesn't blatantly say "UNDERTALE"
I haven't played undertale and i understand it.
Even if that was the case, i'd say enough people have played undertale to prevent it from being an "obscure reference"
Speaking of that, i've already been full spoiled on all three routes of the game. Is it still worth buying?
I don't have folders filled with pictures of fictional characters because I am not a poopy-head.
I have emails filled with the coffee preferences of animal crossing characters.
