look up any word, like wcw:
 
1.
Used by Mcdonalds employees in the UK as a codeword between the crew if an attractive female enters the store.

The word "Cheesecall" has simply manifested over time and it's origins are unknown, but, it is a useful codeword as it seems completely normal to hear someone shout "cheesecall" in a fast food restaurant. The "cheesecall" in question is none the wiser to the antics of her servers.
"Dude, that's a cheesecall!"
