I can hear sweat trickling down your cheek
Your heartbeat sound like Sasquatch feet
Thundering, shaking the concrete

from The Notorious B.I.G. – Who Shot Ya? Lyrics on Rap Genius

Meaning

An extended metaphor to show how much Biggie scares you: you’ll have such a loud heartbeat it’ll sound like Sasquatch or Bigfoot, the giant mythical monster (whereas Biggie probably made the ground thunder like Sasquatch just by going to buy chips at the cornerstore)
