When the accelerator is pushed so far it cant move any more- in some cars it hits a metal bar, or the end of the footwell (which is hopefully made of metal).
Hence the term pedal to the metal. Obviously if you have the accelerator all the way fowards youre gonna be gathering speed...or going fairly fast.
When one pushes the gas pedal to the floor, making the vehicle burst to its highest possible speed. Generally done on straightaways or during drag races, accompanied by a burnout.

Someone who jumps from one relationship immediately into another one.
Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.
Because they jump into relationships immediately after the previous one has ended, serial monogamists typically don't take the time to reflect on their behavior or why their previous relationships failed; thus, they end up making the same relationship mistakes over and over again.
