Odd Language #106: Oh, De[ea]r!

Recently, travelling with co-workers in southeastern British Columbia, we nearly hit a deer. I got to thinking about what is the best way to state that a deer collision is imminent and to take action.

The issue: Because “deer” and “dear” sound the same or similar, it could be difficult between loved ones “Look out! Deer!” could be taken as “Look out, dear!” and followed by a thud. What would your short, understandable wording be?
