droplifting

Droplifting is the opposite of shoplifting; it involves leaving a product or item in a shop, rather than taking one. It has been used by artists and musicians to promote their work for free, whilst some people use droplifting to make political or economic statements. (for example by altering shop's products and then returning them)

Proplifting 

The act of taking leaves or pedals fallen from succulent plants one doesn't own, typically without permission, for the purpose of succulent plant propagation (creating new plants.)

Proplift is a play on the word shoplift, and is used similarly as both a noun and a verb:

proplift (plural "proplifts")
proplifted (past-tense)
proplifting (noun, plural "propliftings"; verb, present participle of "proplift")

Use "proplift", "prop", or "props" to refer to the booty (taken leaves or pedals) of one or more "proplifts",
in the past-tense or abstract, while "proplifted"

Use "proplifting" in the abstract, when describing technique, and for the subreddit "r/proplifting".

"She showed me a proplift, five healthy props, that she had 'proplifted' from the store the other day."

Drop lifting 

Going in to a store, any store, and taking a shit in the bathroom with zero intention of buying anything.

I am always drop lifting at the Chevron. Pretty sure the clerk is on to me.
