Reverse sample ID help

I was digging through records and heard a sample that I KNOW someone else (who I listen to) used this sample. I've racked my brain and can't find a thing. So if someone can please tell me what beat used this sample then I'll tell you what sample it was.

Here's a snippet I recorded.

I was thinking Diamond D, but I couldn't find it. So maybe DITC?
