Meme: They can see your dick pics.
Originator: John Oliver (Last Week Tonight, on HBO)
Cultural Height: 2015-2016
Background: In June of 2013, documents stolen from the NSA by Edward Snowden were released to the public. These documents revealed to the layman extensive government surveillance systems which previously were assumed to not actually exist. (Conspiracy theorists have long warned of such systems. While the rest of the general public likely assumed government agencies were capable of designing and employing them, they perhaps equally assumed this had not actually been done or was not being done indiscriminately.)
In April of 2015, laws which enabled the use of these systems were nearly due to be renewed. However, public interest in the topic had largely waned at this point. In an informal survey, John Oliver - host of Last Week Tonight, a news satire show airing on HBO - found that nobody could even properly recall who Edward Snowden was.
In order to re-ignite the discussion, and inspire the public to action, it was necessary to find an aspect of the government surveillance programs which the layman could intimately relate to. So, in the same survey, respondents were asked how they would feel if the government had obtained access to pictures of their genitalia - i.e.: "dick pics". Of course, the situation was found to be generally undesirable by all.
To bring this into relevance with the discussion of government surveillance, John Oliver traveled to Russia for an interview with Edward Snowden. During the interview, he shared his survey results with Snowden. Then, Oliver proceeded to ask Snowden about the various government surveillance programs which had been brought to light by his leaks. Regarding each, Oliver asked "Can they see my dick?".

This is a fantastic example of how matters of information security can be brought into focus and made relevant to an otherwise ignorant or unconcerned audience. In this case, it was for the general public. However, information security professionals often face similar challenges when having conversations with members of management - especially at higher levels, and with C-level executives.
So, when addressing the level of exposure posed by a certain risk, it may help to ask (or answer) the question: "Can they see the dick pics?"
@Matthew Which, in a way, is more or less the point of my answer. Any question of the form "what can a bad guy do if he has X running on my computer" is essentially "my computer is pwned and needs to be killed with fire".
@Iszi just go with the john oliver answer: "he can see your dick pics"
@Ohnana Yes, indeed. In fact, we should do this to all the 10 Laws of Security:
s/it's not your computer anymore/he can see your dick pics/
