Entering thy vein
  slowing through,
  toked.

  Taking forever,
  get out of my vein,
  flowing up.

  Exit thy vein
  enter my vein,
  take me to insane.

If you don't stay with a single female for the majority of your life, you will constantly play the vein game - she will enter, and drive you insane - over, and over, and over, and over again - different females with different insane side effects. The more insane side effects you have from more females, the more insane you become.. it's like mixing a bunch of bad and good drugs together - it just doesn't work well, and you may even die.

This is not discussing sexual intercourse - but rather the game of flirting - where one look causes a flow through the veins that temporarily injures the heart and respiratory system.
