look up any word, like timebomb:
 
1.
When two chunky people fuck at fat camp.
Girl 1: Yo did they do the chunky fuck?
Girl 2: What?
Girl 1: You know the chunky fuck? Like when two people bone at fat camp...
Girl 2: Naw son I dont think that actually happens.

2.
An overly sized fuck head who stores food in their fat rolls.
"Holy shit man, that chunky fuck just pulled a nugget out of his fat roll!"
