a feeling of being happy or giddy because of being in love. to be so in love you cant walk or think straight or feel like singing or laughing for no other reason then because of a girl/guy. usually caused by simple sweet actions.
if hes all you think about, you smile/blush/giggle everytime he talks to you - he has you swooned.
to swoon someone you are trying to make them have that feeling for you by just holding hands, sending goodmorning beautiful texts, kissing her forehead, saying corny things, letting her wear your hoodie, writing her a song, doing what she likes.
