Catholic gap

slang For a Catholic wedding, the period of time between the end of the wedding ceremony at the church and the start of the reception at another location. This typically happens with an early afternoon wedding and an evening reception. Ugh, what are we going to do during the Catholic gap? We should at least go and get drinks somewhere. Luckily, one of the friends I'm going with lives near the church, so we can hang out at her house during the Catholic gap. Thank goodness for the Catholic gap because I totally forgot their gift at home!
