When visiting a large sculpture, building, or structure of some sort you take a picture while positioning yourself where your dick in comparison looks the same size or larger.
I've collected dickscapes of myself around the world, the Leaning Tower of Pisa, CN Tower, and even the Burj Khalifa.
When playing any shooterbased game, one picks up a sniper and quick scopes the enemy. A dickscope occurs when the bullet hits the area of male genitalia.
