nasterbating

nasty masterbating, usually the kind you accidently witness. Potentially involving unconventional lubes such as sweat from mowing the lawn, old milk, taco drippings, or water from under your fridge.

Walked in on my friend nasterbating the other day, his blow up doll was wrecked. It hurt my soul to witness that.

rasterbating

Resizing an image larger to fit on many pages. These are then printed out and placed side by side to recreate a large poster of the original image. Usually the image is also modified to be made up of small dots, similar to old comics.

"That poster is huge, it must have cost you hundreds."
"No, Wendy taught me about rasterbating, it only ended up costing like $10."
