No one goes to Hell for simply eating a hot dog on Friday. They go to Hell for the sin of Pride, the pride of a person who freely chooses to disobey the teaching of the Church in a matter of faith and/or morals.
God, being perfect, is perfectly Just. He doesn't throw anybody in Hell; Hell is the final destination of those who freely choose to put their own wishes and desires above God's. The only people who go to Hell are people who want to go there.
It was a joke, for heaven's sake. I'm not sure where abstaining from meat falls, since it is a discipline of the Church that's flexible.
The only people who go to Hell are people who want to go there.
Well, we can hope that Hell's population is very small, then.
