When a girl is on her period and all of the sudden she can feel this flow of juices (blood). It is normally silent but it is the most disgusting feeling in the world. Every girl who bleeds knows what this feeling is. No freaking joke.

Gina: thats sick. please say excuse me.
Va: no way, you turkey. you squelched on my FACE last weekend. YOU say excuse me! pervert.
