“Car sex”, then the car is broken
 

"Hi, Tom, It's a long time not seeing you, what's the problem with your car."
"Hi, Jack. I don't know. I had a “car sex” with my girl friend, then the car was broken."
"Hah, Tom, You are just so crazy. Let me check."

"I can't imagine how crazy you were last night. This circuit connectors was shocked off by you.Hah~~~"
"OK.Jack, don't laugh. Tell me how to prevent such a thing, I just do not want you to know all my things."
"OK, Tom. You need this DS708 Tool, I promises you won’t need me again with this tool. And you can be as crazy as you can"
"Really, thank you so much, Jack."
"Sure, you are welcome. Maybe i will try with my girl friend one day. Hah~~"

this does not make sense to me whatsoever
