"Oh, you're so pretty for a black girl."
"Do you speak good English?"
"She has a Jew nose."
Though they might be unintentional, these offensive phrases -- called micro-aggressions -- are heard all too often in everyday conversation. And while they're frequently said in a joking way, the meaning of those words can have lasting negative effects.
In a video created by SheKnows, a group of teen girls explained how micro-aggressions can be hurtful to their self-esteem.
"Because they're micro, because they're very subtle -- they're small -- you feel like you don't have a reason to be upset," says one girl.
"We try to just use jokes to make this less awkward, ease social experiences," adds another. "But... you need to aware of what you're saying and who you're speaking to."
