When you're at a party and all you really want is to get some guacamole dip and chips, but one of your fellow party-goers is drunkingly blocking your path to the guac.
Sarah had gotten her drink and was ready to get some snacks, but unfortunately she was guac-blocked by Cody, who had moved between her and the food.
