Tooling a person for amusement as opposed to practical gain [closed]

Mocking, Baiting, Garden Path

Tooling is really slang (I think American English) and as it also can be slang for having sex it doesn't seem ideal for what you are trying to express.

How about 'subtly mocking' or 'covertly mocking'. Slyly mocking (sly means sneaky, underhand, mean). Or 'baiting' which means deliberately leading someone down a path in order to provoke something or make them look foolish. The expression 'leading someone down the garden path' is also similar.

~Sounds like a bitch!

Mocking Definition To ridicule or poke fun at someone.

Baiting To deliberately lead someone on to make them look foolish.

Tool does indeed have a meaning of mistreating someone, though this is slang that many speakers may not know or commonly encounter.

Green's Dictionary of Slang (2011) has this entry under "tool, v.":

tool (around) (v.) (US campus)

to mistreat someone.

1967–8 Baker et al. CUSS 212: Tooled (around) Treated unfairly on an exam. 1988 Eble Campus Sl. Oct. 10: tool – ridicule […] Elizabeth was tooled by Doug because he never called her after she had professed her love for him.

In a similar vein to the second quote, the novel Going Vintage by Lindsey Leavitt has this about a recent ex-boyfriend of the speaker:

" [...] And I've already been there, done that, got that I WAS TOOLED BY JEREMY MCTOOLERSON T-shirt. And look what good came of it," I say.

That said, this may instead be a clipped instance of tool off or tool out, also from Green:

tool off (v.) (also tool out)

to leave, to go away; to abandon, to desert.

Then there are other senses of tool, like tooling about or tooling around, meaning to behave aimlessly or waste time (also Green).

So it is possible to use tool to suggest mistreatment on Alice's part to Bob, though it will sound unusual to many English speakers and may not hold all the nuances you want. (Mistreatment need not be deliberate, for instance.)
