A prefix denoting less than total commitment to one's ideology or belief system. It could be one believes in it but does not act on it, or does the bare minimum, or less, necessary to be able to claim that ideology, or merely sympathizes with an ideology and associates with its adherents. Originally used by Mormons to refer to vacillating or insincere members, and non-Mormon allies of the Church.
She says she's a Christian and believes in Jesus but she only goes to church on Easter and she hasn't actually read the Bible. I guess she's a Jack Christian.

a hot guy that will love you forever, and will never get over you. he will never cheat as long as he is with you. even though he is shy and gets nervous around you, he is still the best bf to have over any jerk. he has many girls that are friends and you probably will get jealous because of that, but dont worry he will still want you. he has the dark justin bieber hair that every girl loves when he flicks it, and has the most sexiest body you will ever see, plus he will always try to impress you, but after a mistake in front of you he may lose confidence :) that and he is an amazing kisser :D <3
