Supposedly a game played by bored army recruits in the field. Someone takes out an MRE cracker and the group starts to masturbate onto it. Whoever blows their wad last is the loser, and they must eat the cracker.
Soldier 1: Dude, this is boring, let's play some Salty Cracker!
Soldier 2: OK! I'll grab one from my MRE.
Soldier 3: Umm... are you guys whacking it on a cracker?
Soldiers 1+2: Hell yeah, wanna join?
Soldier 3: Sure!
Soldiers 1+2: Haha, you lose, EAT IT BITCH!
Soldier 3 gags.
