When you've eaten alot and afterwards you feel sleepy or actually have a nap/fall asleep. Taken from a scientific finding that sharks fall asleep after eating due to chemicals in their brain.
" ohhh i've got the shark, i'm going for a nap "
OR
" i think i've got the shark"
OR
" zzzzzzzzzzz " < the shark just got you.
