A condition where on long deployments away from girlfriend, wife or booty call, a soldier will masturbate with a strong grip and furious motions. Side effects are lasting longer in bed upon returning because compared to infantry grip, any pussy feels loose.
Soldier- have you been banging a black guy while I've been gone?
Girl- no baby! Its just your infantry grip!
