Give his bicep a hug! Guys will stand straight on to the camera- this allows the camera to capture their big broad shoulders (and helps to hide if they have a belly pouch). Hands in their pockets (thumbs in or thumbs out).

Ladies- You can then slide into their side and give their big ole bicep a squeeze. Bend a knee or cross your ankles to add some visual interest. 

This is a great pose for women who want to hide some width, or just anyone who wants to snuggle up to their man.
