look up any word, like sex:
 
1.
What soccer moms say when their son has just done something AWFUL. This statement implies that any negative behavior should be excused on the grounds that boys are always doing things that are wrong, and need to be treated with a degree of leniency that borders on insanity.
Bystander: Oh my God, that kid is raping a nun!!
Soccer Mom: <Fake Laugh> Oh, well, you know. Boys will be boys. I'm sure he just had a hard day at school.

2.
An out-dated catch phrase that was used to excuse adolecent mischief, such as stealing a cooling pie from a kitchen window, or not eating your vegetables. Outdated because adolecent mischief now includes rape, murder, car theft, drug abuse, and arson. Such things therefore require severe legal punishments in a criminal court instead of simply writing these heinous acts off as "boys will be boys."
"Oh no! Two armed students have massacred a bunch of fellow students!!!"

"Well, boys will be boys..."

3.
An excuse that people make for a young guy doing something stupid.
High-school principal: "Your son cut class to smoke a joint and tag the women's locker room. We caught him in there, in a compromising position with two girls."

Mother of 18-year-old: "Well, he shouldn't be doing that...but boys will be boys, I suppose."

The biggest, pithiest, bullshittest excuse for male behavior that is otherwise legally/morally unacceptable from birth to the grave. Covers socially perverse actions that no girl could ever get away with without the label to the effect of "weird/evil" or "whore", i.e. like fighting, having promiscuous sex, cruelty to people and animals, or any behavior combining selfishness and aggression.
Teacher 1: Last week, one of my students mooned the class. When I called his father, he apologized, laughed and said "Boys will be boys."
Teacher 2: True enough.
Teacher 1: A few days later, his daughter did the same thing. He came down, mortified, and spanked her right in the principal's office.
Teacher 2: Sounds fair.
