What does "tea juice" mean in this context?

Question

I heard in a YouTube video this line:

We could say for a vegan it's bad to drink milk. But a non-vegan who doesn't abide by that moral code will drink all the tea juice they want. (source)

It seems "tea/T juice" here refers to milk, but what does it mean exactly? Why is milk called "tea/T juice"?

Answer 1

I think he's humorously referring to milk as "teat juice" (not "tea juice") because it is squeezed from a cow's teats (i.e., udders).
