Counter Tips

Try not to target him if he has his Defensive Curl on - as he will take much less damage, and he'll also return some damage back to you.
Most Rammus players build heavy armor. This will make him vulnerable to AP damage.
Try to stand amongst creeps to avoid getting knocked-back by Rammus's Powerball.
Taking cleanse or buying a Quicksilver Sash will let you immediately cure his taunt.
