What is a block hash?

I did a direct deal with someone, and they told me to send over the block hash. What is this? I assume its something they can use to look up the transaction.

It's a big block of cannabis resin. Oh wait.
A Block hash. It's your transaction ID.
The cannabis resin is way more fun though.

Transaction hash of your bitcoin delivery. Unique for each tx and can be referred to in the blockchain.
