Scrounging

[Kit]

British slang for obtaining goods and services without having to pay for them. The word can be used in two rather different ways:
1 If it is for personal advantage then the word has certain negative implications, that the person doing the
[scrounging] is not [wholly] trustworthy;
2 If it is to further a project at work or to obtain goods, materials or money for [a charity] then there can be a certain
amount of admiration.

[Ernesto]

The act or [process] of looking for weed [anywhere] and [everywhere].

[Justin Bieber]
