Experienced a difficult
time or unique timebwith another person, usually your friend or, when at
work, your partner(s).
It usually brings the
people involved a bit closer to each other as they had a shared experience together.
We shared a foxhole together the night the
car broke down and we had to walk 5 miles through the
forest to get the the nearest gas station.
The patient was bleeding, vomiting, and pretty much dying in
front of us. After working our asses off, getting covered in her blood and vomit, we saved her life. We shared a foxhole that night.
