> スノーヒョウ同性愛者であります。 アニメは悪です

You're not around to read this anymore but this roughly means "A snowleopardhomosexual object is present. Anime is evil."

The lack of spaces is to convey that スノーヒョウ同性愛者 is ungrammatical. "Object is present" is to convey that あります is not used for living beings.

I hope you made this mug and showed it off to Japanese people. They will be amused. Or maybe horrified.
