I think is a word that you would use to describe something something that your not sure about. For example, you, in the middle of a 6 hour drive in the middle of no where and you say, "Hey mom, I THINK I have to go take a shit." Then she scoldes you for like 35 minutes fro not using the bathroom at home like she asked, and the moment you step out of the car of the sketchy gas station, you fart. The thing is, you really thought that you had to poop, but you didnt. Same thing when she said it too. I THINK (that im in love with you)
