I have a friend who is an excellent non-native English speaker. However, when agreeing emphatically via text message, he will sometimes say "exact-fucking-ly!" This sounds odd compared to "abso-fucking-lutely," which is much more commonly used, but means "yes" instead of "precisely."
What is another exclamation (with or without profanity, but carrying the same emphasis) I could suggest he use?
Additional details: My friend and I live in the San Francisco Bay Area. Colloquialisms compatible with English spoken in any North American locality should be acceptable. To be clear, I AM indeed looking for opinions, but some phrases work better than others.
