You can accidentally throw someone under the bus. But, bus fucking someone is on purpose.
Ted: I didn't throw him under the bus. I hate that asshole. I bus fucked him, right to the bosses face!
Dude, we've been busfucked for over 20 minutes. I'm thinking about running over the next fucking kid that gets on that damn bus. I'm sure the judge will understand.
Bro I got busfucked and missed my train so I'm gonna chill and drink some gold tops in my car till the next one comes.
"Oh, you know, mass transit- I got busfucked."
however, the ending "fucked" is also interchangeable with random words like:
LEAF fucked, WIND fucked, STREET fucked, etc.
basically it's when you get fucked over. not FUCK FUCK, but fucked over.
"SHIT! the wind is so strong. we just got wind fucked!"
