grow teeth
v. phr.— «Mickelson taps in for par on the 9th to finish the front nine on -3. Meanwhile on the 11th, John Daly puts his considerable weight behind an effort to slash out of knee-high rough. It’s a great effort, but “grows teeth,” as they say in America, and comes to a stand-still a couple of inches short of the dancefloor.» —“The Open—live!” by Barry Glendenning Guardian (United Kingdom) July 20, 2006.
