First, make sure YOU know the definitions WITHOUT looking them up.

Try asking clarifying questions to push your manager to expand their understanding. Some ideas are: "What do you mean by X in that context?" "Thats interesting, how does that work exactly?" "I've heard of x used as y, how would it be used in your example?"

Go rogue and publish a glossary of techncial terms with public references and post it up in your office.

Clarity is key. If your manager is using terms incorrectly, they are likely confusing others on the team or representing the team inconsistently. In the end they need to get their skills up, get more info, or get out of the way. IMHO.
