On top of the shirt, it says {ngItlh 47} - whatever that may mean. Maybe
it's just English with Klingon letters, so that might be "fix 47"?

47 has a special meaning in Star Trek:

The other word is {ngISwI'}. Looks Klingon, but is not. It's combined
with the letter 12.

Could this be a new word out in the wild?
