The annoying tendency for poured milk to bounce off breakfast cereal and onto the table or counter.
Man, I had my IRS 1040 all filled out and signed when a lactodeflection off my corn flakes splattered it with milk. I knew I shouldn't do taxes at breakfast.
- Yo Bob, where did you go? We searched everywhere for you at the party.
- I had to change my pants man, had a little lactcident after downing two White Russians.
The accidental mammary fluid letdown that can sometimes occur to a lactating woman when she hears any baby cry and it results in 2 very embarrassing wet spots on her shirt. Woman may try to stave off or prevent the unwanted flow using various methods which may include: pressing very firmly over nipples area, attempting mind-over-matter Jedi tricks, or absconding to a private area to let nature take her course.
Can be compared with, and about as humiliating as, pee-pants from laughing too hard (which, sadly amongst non-senior adults, also happens more frequently to women who have given birth).
Mom 1: "It's 80 degrees out today, why are you shivering with your arms across your chest?"
Mom 2: "Naw, damnit, that baby is crying and it gave me a lactcident, I'm gonna have to grab a new blouse before we hit the shops."
