15.
The act of spontaneous wandering that does not have a particular destination in mind, however this action results in wondrous, often life changing experiences.
One time a friend of mine went to the store to get some cupcake with her friend. They did not have them, so they went to the next city and had no luck there. They continued to hop different stores in search of cupcakes... until they knew it they were watching the beautiful sun rise on the Santa Cruz beach.

Another experience, was when a friend of mine went to go cupcaking along the coast, and discovered a beached whale. Seeing this was life changing to say the very least!

texting someone while in the same house or room as them while in a group of people. usually to gossip or flirt.
you can tell when two people are cupcaking by watching them. if person A and person B are constantly looking at each other after reading a text to if right after person A sends a text person B looks at his/her phone.

When good friends get together, go to Wal-Mart at 11:30pm to buy the mix & sprinkles, decorate them all pretty-ful, write on post cards silly notes like "We were going to TP your house, but we decided to cup-cake you instead, ENJOY!", leaving them on people's door steps, ringing the doorbell, and hauling ass. Hiding behind a bush/trash can/underneath a car is always the best part of cup-caking. The reactions of the neighbors is also a delight! Will they eat it? Throw it and try to find the asshole teenagers commiting random acts of kindness? The intensity is overwhelming.
"My friends and I went cup-caking last night"

"Is that where a midget eats out a porn star?"

"No it's when good friends get together, go to wal- etc, etc."
