one foot on the bridge

Meaning that a person is so stressed out they're even considering jumping off a bridge.
For stressed out students or workers (mainly made for college students, especially around finals time).
Not meant to be taken seriously!!! IT IS A JOKE.

"Hey Roxanne, you okay? "
Roxanne: "Nah man, it's finals week. Between this and work, I've already got one foot on the bridge.."
