a case of the 'don't know ya's 

When someone who you have met on several previous occasions acts like they don't know you when they see you in a different setting.

Susie: Hey, isn't that Joe from shipping who just walked past our table? He didn't even say, "Hello". I just talked to him earlier today!
Jenny: Yeah...he's got a case of the 'Don't Know Ya's.

Lower Case Y 

The XY chromosome genetically defines the male as heterogometic.

This term implies that someone, or one of their actions, is a little feminine or not quite worthy of full maleness.

The way you jumped over that puddle was very Lower Case Y.

sad case 

A contemptible and depraved individual, one whose actions are an embarrassment to himself and/or others.

That kid is a level SR130 on Halo 4 and it's only been out for a month. What a sad case.

That kid spends half his days on Facebook rummaging through his news feed. What a sad case.

That girl cares about what people say on Facebook. What a sad case.
