ethics of announcing someones outs when all-in?

[elliot]

NLHE tournament, four players left, top three pay.

blinds 1k/2k, average stack 25k

lucksack on the button shoves preflop, frat boy in the SB calls

lucksack turns over Q [img]/images/graemlins/spade.gif[/img] T [img]/images/graemlins/spade.gif[/img]

frat boy has K [img]/images/graemlins/diamond.gif[/img] K [img]/images/graemlins/spade.gif[/img]

flop: Q 8 x rainbow

turn : 9

without even thinking about it i laugh and say "needs a queen ten or jack, hes got a bunch of outs"

river is the jack and frat boy predictably goes nuts, as he is leaving, he semi gets in my face and says "you know calling out cards like that is really not f*cking cool so dont do it again"

i'm obviously assuming the beat had him steaming, but is there anything dickish/unethical about what i had done? (it wasnt to try and be a wannabe tv douchebag, it was genuine suprise at the number of outs lucksack had going into the river)
