If the choice is constrained to bud or butt then butt is the better choice. However the best answer is "cut in line". A google search for each option yields these results: "he bud in line" = 4 hits "he butt in line" = 76 hits "he cut in line" = 104,000 hits
You used incorrect grammar in the first two searches. Try "he budded in line" or "he buds in line." Likewise "butted" or "butts." Only "cut" has the correct tense here, which is why your results are so skewed. That said, it's still the most common term. Just not as clear-cut as you thought.
