The meme appears to combine elements from different pop culture references, one being the phrase 'FIF' which is humorously associated with a particular way of asserting one's right against self-incrimination (and is derived from a comical distortion of 'Fifth', referring to the Fifth Amendment). The character holding the sign with 'FIF' written on it, and the style of the image suggest a blend of courtroom setting with a hip hop influence, which could be funny to those who recognize the references.
