brother-in-law
v. phr.— «That said, some players have found ways to make it look as if they’re working a lot harder than they actually are. It usually happens in training camp or, occasionally, in exhibitions. There’s even a name for it: brother-in-lawing. To brother-in-law means to have an agreement with the guy across the line of scrimmage, an understanding that you’re both going to take the play off, pretending to play hard when you’re just going through the motions. When it happens, it usually takes place in practice or exhibitions, and often in the trenches.» —“Off-Season Starts Early for Some” by Sam Farmer Los Angeles Times Dec. 30, 2005.
