Catholic Tabernacle. Box on the alter of Catholic Church where the host is kept. The host being the representation of the body of Christ in the typical form of a wafer/cracker that is handed out to parishioners during a Catholic Mass. So a snack. The place where the snacks are kept.
When a brother is grinding with a girl in a club whilst simultaneously the girl is facing the other direction , tossing off another different brother in a "snooker cue" motion with the hand maintained in a parallel position. The covert way in which this is done means that both dudes can be oblivious to the other , however when one realises he will be locked in position - unable to make the next move - hence both guys are effectively snookered
"Oh look at that chick, playing some quality snookering - "
" that fat girl is so large the dude can't see he is totally snookered !"
Variant on the common term ‘cradle snatching’ for someone who is sweet on a much younger honey. If you are not in it for the long haul but simply want to sample the youth for a short while, you are ‘cradle snacking’.
