Grows Hard 

When you're dedication to growing is on a whole other level.

(Like "Go hard" but ya growing)

Absence makes the dick grow harder 

When someone becomes more attractive to you when you haven’t seen them in a long time. Basically, your image of them in your head becomes more attractive.

Matthew: I thought you were over Terrry?
Sam: I haven’t seen him in a month, and you know what they say, absence makes the dick grow harder.

Hardcore Growl 

The opposite of a hardcore scream. A hardcore growl is a low, rumbling sound in the throat. It works better with grindcore or emo-core style music. Not so much on the level of regular screamo. For example: You couldn't growl to a Rise Against song. However, the screaming done my Alesana works well because they're more hardcore.

Dude, Denny Diablo from Alesana is amazing at hardcore growling
