When you prowl from coffee shop to coffee shop, in a search to find a quiet place to work, OR when you use the shop as a resting point on a longer day excursion.
Concisely, when you prowl through coffee shops looking for temporary warmth and/or free wifi.
I pretty much just coffeeshopped around the town today. The wind was really brutal, so whenever my fingers went numb, I just ducked inside the nearest one.
Yeah, I coffeeshopped for awhile, and the one on Grovenser's Street has outlets for my laptop charger, so I worked there for a bit.
