To ask somone to think again. From the British Television game show Play Your Cards Right where contestants had to guess if the next card turned up was higher or lower than the previous card. A slow contestant with a 2 of Clubs might say "lower?" and the audience would scream "HIGHER!!".
Friend: Want to go to Mulligan's for a pint?
No. 1: Higher.
Friend: Why? They love us in Mulligan's.
No. 1: Higher, I got thrown out last night.
Pathetic attempt at the simple word 'raise.' Heard in southern california. Actually used by adults, if you can believe it.
"Aww man - they highered the price of weed!"
"Maybe that's a good thing"
exclamation of the word hi, said especially in an over-excited way!! Also said when having sun tan lotion put on your back...
(sun tan lotion being put on...) lower (so hand goes lower), left (so hand goes left), right (so hand goes right) higher (so HIGHER is said and hand is left where it is) leading to a great fit of giggles!!
