Variations of any statements including the phrase(s):
"It [usually referring to someone's attire or method of carry] just screams 'gun.'"
"It doesn't scream 'gun.'"
Sorry, but even when I see some overweight, bearded guy attired in the latest 5-11 pants with polo shirt covered with a tan safari vest, coolly sporting Oakley Gascan shades and trying hard to look like a retired Blackwater contractor just back from downrange, no one or nothing is screaming "gun" to me or anyone else. Now, do most of us know this guy is likely packing? And if we see some dude trying to be the gray man and blend in, do we automatically assume that person doesn't have a gun? Phrases that facilitate buying into stereotypes or "common knowledge" can be dangerous.
