heart: I'm hard, veiny, and filled with blood. I throb and pulsate too. I usually stop throbbing, when I'm not inside of you. What am I? A heart of course!
An amazing game that you should REALLY go play
"oh yeah go play Jimmy and the Pulsating Mass it's an awesome game man"
Something that pulses or has pulsing qualities.
I just need this. This pulse. This pulsating…ness? Pulsatingness. In my head. I need pulsatingness.
