Answer 1

its not used correctly, its meant to imply sexual innuendo... or a dbl entendre... but it just didn't work cause you wre already talking about sex!

he's an idiot with sex on his mind!

"i love juicy meat...if you know what i mean"..thats clearly some [stupid] sexual innuendo...but that actually make sense

Answer 2

nope.. only he knows. but play along
