going into battle 

banging a chick that's on her period.
When the ancient warriors "went into battle" many where slaughtered or came out covered in blood. Hense the term "going into battle".

Her - No, not tonight Aunt Flow is visiting...
Him - well then I guess I'll be going into Battle then baby!!!

going into battle bare naked 

1) Idiom for going into an arguement without any comebacks or plans to do anything if you're losing.

2) going into any battle in a game, fully unprepared for the strength of the opponent. (Not enough armor, not strong enough, etc.)

1) "Lidia's never going to get out of that arguement, she's going into battle bare naked!"
2) "Sockcat43 is just unprepared for this boss. He's going into battle bare naked!"
