Tweets
Looking for tweets for thermos.

plethora It's the same deduction of heat no matter where the soup landed, which is tricky, particularly on a turn. Dec 8, 2008
reesetee Not if it didn't take into account the turn before the gate and the fact that Torres' feet touched the white tape. Dec 7, 2008
bilby Do you think the soup's still warm? Dec 6, 2008
chained_bear What? No! Dec 5, 2008
mollusque Hey c_b, did you know that Dara Torres has a thermos that's 41 years old? Dec 5, 2008
chained_bear Hey, thanks for posting. I didn't know about thermos. I'll have to add that to my list. Dec 5, 2008
dontcry *singing* "I'm going to buy a Thermos for you... No ordinary Thermos for you..." *sits in tub and squirts water into the air with hands* Dec 5, 2008
sionnach yes; according to Abraxis -come back all is forgiven- Zugzwang, the word is antonomasia (see his comment on c_b's list) Dec 5, 2008
sarra Metafilter wondered too: Question on generic terminology
Wikipedia has an article on the genericized trademark
And the word might be antonomasia. Dec 5, 2008
chained_bear I was updating my list and in the process, did that three times. Apparently I have no short-term memory whatsoever.
Hey! I should add thermos to my list! Dec 5, 2008
reesetee I'm jealous of c_b's list. I think of additions darn near every day, then forget them almost immediately before I have a chance to go there. Dec 5, 2008
chained_bear Hot damn. I never knew that about thermos. Thanks! Dec 5, 2008
bilby Chained_bear has a Trade Names list. Plenty of comments there but not much about the phenomenon itself. Dec 5, 2008
frindley Indeed it is. It belongs to the same rhetorical class as kleenex and bandaid and esky but it's too early in the morning for me to recall what that's called. Dec 5, 2008
reesetee Yes, it's a brand name, but I believe it's used by some as a generic term for an insulated vacuum flask.
Also, as I'm sure you know, it was long ago a sanctuary for the Aetolian League. Dec 4, 2008
bilby Was/is this a brand name rather than a generic name? Dec 4, 2008
