Primarily heard in US. Timmy is such a teacher's pet, always ready to drop a dime on any of the other students he thinks are misbehaving.

drop a dime
To snitch, to betray. Once upon a time, pay phones in enclosed booths could be found on most urban streets as well as in other public areas. Vandalism was rare, so the phones worked, and equally surprising to us today, local calls cost a dime. A person who wanted to report something to the authorities that he or she didn't want anyone to overhear and didn't want the call traced located a secluded phone booth and deposited ten cents. That's the dime that was dropped down the coin slot. The dime-dropper took a big chance, because if the droppee found out, the rat stood a good chance of being exterminated.
