Just ya picture though, you still taped in a lake
I'm laughing;

from Cam'ron – Down and Out Lyrics on Rap Genius

Meaning

There’s an empty casket at the wake since they couldn’t find the body, so only a picture is present to represent the deceased.
Meanwhile, Cam knows where the body is since he duct taped the guy’s mouth then threw the body in a lake (does little dance)

Similar theme in Jay-Z’s 22 Two’s:

At your wake as I peek in
Look in your casket feeling sarcastic
“Look at him, still sleepin”
