Let's have some fun and grep the linux source code (linux-3.0.y) for bad words :-)
$grep -i -r -B 2 -A 2 fuck *
drivers/ide/cmd640.c- * of IDE interfaces using the CMD Technologies 0640 IDE interface chip.
drivers/ide/cmd640.c: * These chips are basically fucked by design, and getting this driver
drivers/ide/cmd640.c- * to work on every motherboard design that uses this screwed chip seems
drivers/ide/cmd640.c- * bloody well impossible. However, we're still trying.
lib/vsprintf.c-/* vsprintf.c -- Lars Wirzenius & Linus Torvalds. */
lib/vsprintf.c: * Wirzenius wrote this portably, Torvalds fucked it up :-)
