[last name]thirty

last namethirty is a time when any particular individual shows up to work. Might be 9am. Might be 9:30am. Depends on a number of factors and the individual (i.e. border, traffic, weather, illness, bad burrito, etc.).

Employee 1: Where's last name at? What time is he coming in?
Employee 2: I don't know.. maybe last namethirty? He texted last night and mentioned something about having some bad Mexican food at this new place... might be a bad burrito slowing him down...

Dirty thirty

When a person reaches the age of thirty and uses promiscuity to try and convince people that he and or she was not a prude.

She doesn’t want anyone to know that she’s just a dirty thirty.
