The solutions to the clues are
Flow thickly = OOZE Carpe, in carpe diem = SEIZE Ground floors of hotels = LOBBIES Mighty's partner = HIGH Prolonged attack = SIEGE Sound bacon makes when you put it in the pan = SIZZLE Fixate on = OBSESS The Beverly ___ (60's sitcom) = HILLBILLIES
The logical leap (hinted at by the title, among other things) is that these words can all be spelled out by turning digits on a calculator upside-down (see here). Converting each line to digits in this manner gives
 (2-3/4)  (2-3/5)  (3-4/7)  (3-4/4)  (4-5/5)  (3-4/6)  (4/6)  (6-7/11)
Indexing the numbers in parentheses into the calculator digits gives 20, 21, 18, 14, 15, 22, 5, 18, and converting these back to letters alphanumerically results in the answer TURNOVER.
