It is ok to send this nice Facebook emoticon to your crush. It is the holiday season is it not? Sending this Under the Mistletoe kissing will let them know your feelings for them. If not it is a cute way to show them. If they do not reciprocate when you send this Facebook Messenger Emoticon, you can just say it is the holiday season! Either way it is a great way to send this emoticon as you might get one back and that will make for a joyous day!
