The primary assistant to a typically small- to medium-time neighborhood crystal meth dealer, quite often responsible for keeping the dealer themselves out of trouble and the operation running and profitable (the term profit subject to dealers' perceptions). This role is similar to the 'Sketchatary' in association with a dealer but is different in that the individual providing support is doing so out of a genuine interest for the dealer and their operation, as they often begin their arrangement based on prior trust and experiences as friends.

Roles of the average sketchetary typically include:
- Mobile phone receptionist
- Schedule coordinator
- Code-keeper (combinations, PIN's, etc)
- Chauffeur
- Gopher
- Security guard
- Accountant
- Personal assistant (grooming, wardrobe, etc)
- Party planner (and later, Party pooper)
- Voice of reason
- Whipping boy/Fall-guy

The job requires a high level of intrusion into their dealers' lives, often mistaken for being overly nosy or snooping about; to do their job well they must know what is going on, what comes in, what goes out, who has what and where at most times. Without a high level of trust between a dealer and their chosen assistant then neither one can do their job right.

If a romantic (or purely physical) relationship develops then the Sketchetary title does not apply; then they become just another skank looking for a free ride.

Sometimes a Sketchetary is referred to by the short-hand "SKTY", pronounced "skitty."

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.
