Hot girl: Hm­mm, that’s a synec­dochi­cal head­line.
Hot boyfriend: What does “synec­dochi­cal” mean?
Hot girl: Well, synec­doche is a fig­ure of speech where a part of some­thing is used to stand for the whole of it, or where the whole of some­thing is used to stand for a part of it. So, in that news­pa­per that guy is read­ing, when they say, “De­troit us­es bailout mon­ey,” they re­al­ly are talk­ing about the au­to­mo­bile in­dus­try, not all of De­troit. They’re us­ing all of De­troit to re­fer to a ma­jor part of De­troit’s econ­o­my. Synec­doche. They use this in news­pa­pers all the time, come to think of it.
Hot boyfriend, smil­ing but clear­ly no longer fol­low­ing her: Girl, look at that vo­cab­u­lary! You’re so smart.
Hot girl, flat­ly: Yes, yes, I’m very smart. Now shut up about that and tell me how pret­ty I am.
