PBI 

Poor Bloody Infantry. The soldiers who get to hold ground while every other branch of the armed forces shoots at them.

"At 10 p.m. the 'Flying Pig' dropped a round in our front line at X 9 D 5 2. The trench was completely wrecked—the crater formed being 14 feet deep and 25 feet across. It is consoling to think that over 40 rounds have been fired from this gun into the enemy trenches during the last week.

(Very consoling to the PBI)"

My girl wouldn't stop farting in bed last night so I decided to role play as a PBI agent and I executed a search warrant on her anus.
