The wrong way to hold a skateboard (by the trucks, with grip tape rubbing against your pants).
Typical of people who spend more time carrying their skateboard around the mall as a fashion accessory instead of actually riding it.
The poseur was easy to spot because their pants had been sanded down near the waist due to constant mall grabbing.

Invited to a birthday party, wedding, baby or bridal shower by someone rarely see or talk to just to bring a gift. Invite is usually by mass email. Not really friends with the person.
Receive mass email invite to someone's birthday party, whom I have not spoken to in a year. Tried to maintain contact or get together, but person too busy to get together, usually makes no effort. Told by friend when people who make no effort to call or stay in contact, but send out a mass birthday or shower e-vite, are gift grabbing.

Attend baby shower, mother to be barely acknowledges your presence, but happy to take the gift you spent your money on. Barely or does not say "thank you", receive a thank you note via email by the grandmother to be. Blatant gift grab.
