Someone that freaks out or has adverse effects that other people around them don't have on a light amount of a drink or substance (not just once but always, something they're known for) is about as close you get to what somebody means when they say somebody is a lightweight. So a guy drinking a quart of wine and not being able to stand up is not a lightweight, because most people shouldn't have good balance after drinking a quart of wine.
The lightweight is falling all over the place or making a chaotic environment every time he/she has a couple shots or beers, or hits of a joint.

The girl that thought she was Chyna, the pro wrestler, the one blocking the stairway and loudly asking everyone that wasn't out there with her what the hell is going on wasn't doing anything physically clumsy, but was still making the same kind of chaotic environment that somebody would make if they were stumbling around. Not everybody gets that way after a few drinks, so she must be a lightweight.

The girl that thinks she is Chyna, the pro wrestler, the one blocking the stairway and asking loudly to everyone that isn't outside with her What the hell is going on might not be stumbling or falling all over the place, but she's making an environment just as chaotic as someone doing that, and the worst thing about it is at least someone stumbling and falling is at least aware of what they're doing when it becomes irritating or chaotic. A lightweight is also someone that gets even mouthier than they already are sober when they are drunk or on something, someone that gets beer muscles or beer courage.
