As for Weiss, I have yet to find a character to ship her with. I know people ship her with Blake, but I ship Blake with Yang.

She's been shipped with Ruby.
[quote]-Weiss is a little too tsundere to show it and you know it[/quote]

That luggage-rack was a little too convienently placed by "the smartest girl of the class", eh?

Theory: The luggage rack appeared AFTER Yang left. And Weiss was pretty much standing right next to said rack, likely within earshot.
Weiss seems like the kind to panic in a social situation (not unlike Ruby), opting for a rather contrieved way of appearing dominant and/or 'impressive'.
--Likely, she hoped Ruby would just bump into the rack, and not knock things over and become 'crater face' (a name Weiss has never called her, perhaps due to guilt of causing the situation and then letting it get way out of hand).

She yells at them, [i]because she cares[/i].
As for other numbskulls that Weiss could have easily told-off... Cardin, Penny, and Sun in particular.
