Dating someone's sibling because you cannot date them for various reasons
"Bro, you can't date Sarah"
"That's fine, I'll just date her sister"
"Same DNA, same P in A! Next best thing!"
Exactly, it's right, the same one, no different at all.
We can have a spicy Thai dinner at a Thai restaurant or at a Thai street-sided food cart. Its taste could have been a same same, but same!
"Same to same" is a phrase used to indicate agreement with a statement in a playful or silly manner. It suggests that the speaker is in the same situation or has a similar experience, and is acknowledging this by saying "same to same." The phrase implies that both parties are on the same page and understanding each other in a lighthearted way.
"I can't afford to go out for dinner tonight, same to same?" said Jane, acknowledging her tight budget in a humorous way.
