I think the usage of relay and relayer are very confusing. If you look up the definition of relay it says:

relay (v.) to receive and pass on

The key in the definition is the receiving portion. I believe that because a relayer should receive data, the term should be used to describe what are now called service nodes. The user / dapp are not relaying any data, they are the original source.

My proposal:

Relay: act of executing the tx on the user's behalf
Relayer: server that receives meta-txs and executes valid meta-txs
Delegation: act of sending meta-tx away to off chain 2nd layer / service node
Delegate Contract: a smart contract that can issue txs for an approved user
