verb
to have a strong liking for; to take great pleasure in.
This sense of 'stab' derives from its earlier meaning of 'to sexually penetrate', apparently by way of an analogy between liking a thing intensely and sticking one's member into it.
Can be intensified as 'poo stab' (a reference to anal sex), which means to REALLY like something.
