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
[3200] (2-3/4)
[32135] (2-3/5)
[5318807] (3-4/7)
[4614] (3-4/4)
[36315] (4-5/5)
[372215] (3-4/6)
[553580] (4/6)
[53177187714] (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.
