A phrase used during World War I to describe men climbing out of their trenches to attack the opposing trenches. Before running into a wall of rifle and machine gun fire, the attackers were usually given a warm meal, a bit of rum, and said potential goodbyes to each other before facing almost certain death. It was considered the greatest test a man could ever face.
"As time passed, apprehension became acute as I weighed my chances for surviving the attack. No; I could not so easily give up. The grip of life was tightening on me and more than ever I wanted to live." -British Liaison Officer before going over the top at the Third Battle of Ypres

This can only be done when your girlfriend is a babysitter. While she is at work, you go visit her and have sex in the homeowners bed. It is best pulled off when the man of the house walks in the room as you are putting on your shoes.
Friend 1- "Tyler was having sex with his girlfriend yesterday and pops almost caught them."

Friend 2-"At what point did he catch them?"

Friend 1-"Well they were done and he was just putting on his shoes.

Friend 2"Oh! Its all good. They were just going over French.
