Twitter Tussle is a unique third party tool that allows you to compare two words to see which is getting more love on the social networking site. In order to find out which word is getting Tweeted more often, simply type in the two words in the given spaces and then press the tussle button.
Giving the Twitter Tussle a fun twist, two birds that are meant to represent each word duke it out for the top spot. Once the cloud settles and the fight concludes, it's revealed which word has a higher TPM (Tweets per minute). This is definitely an interesting way to find out what's more popular.
