ii) To spit, usually involving mucus.
i) Look at that Skreb, what an idiot.

ii) I just hocked a skreb on the pavement.

Get the skreb mug.
A socially regressive term that occurs when one person in a friendship with another person sees the other person make a mistake, but is too afraid to call them out in any sort of lighthearted criticism for fear of a loss of friendship.

The term has an addictive characteristic in how the word sounds somewhat silly or cool, and therefore is used in repetition even by people who have a disdain for the word itself.

So, essentially, if you are a fan of this word, you're a skreb.

Get the skreb mug.
The remains of a discarded cigarette with at least 10% left unsmoked. Often found down on the park, stained with urine or white lightning.

Sometimes, desperate or trampy people may spark up a skreb end and finish it off. With any luck, they will die of dysentery as a result.
'You know what you two need?'
