Food Stalking
The act of observing the tables around you at a restaurant and ordering what the other diners are eating.
When Leo the waiter at Grand Lux Cafe asked Nancy if she'd like to start with an appetizer, she was totally food stalking when she ordered what the table next to her was having.
Food for Stalk
Anything that provides mental stimulus for creeping. Usually a Facebook newsfeed.
(inner monologue of a high/bored person):Laying here watching 'Hoarders' is not enough right now, I should read something. Food for thought on Wikipedia or food for stalk on Facebook?
