The easy way to get this achievement is on a sword match. Make sure you have sticky grenades, and have somebody follow you. Usually someone chasing you runs in a straight line towards you. Once they are lined up simply throw your grenade straight at him.
Another easy way to get this is on the map guardian... Just camp grenades spawn near the lift and run towards anyone who gets close to you and nade them.. If you keep trying you should be able to get it within the first 4 minutes.
