A dietchley (deet-ch-lee) is a person who is consistently late and has little to no regard for other people’s time, but people tolerate it because they maintain a good presence.
He’s being such a dietchley. I’m going to beat his ass.
A hardo is a person who tries extremely hard at everything. Most times a hardo will try very hard at things that do not require excessive effort. For example, sports practices, gym class, etc.
Wow did you see Jack at practice today? What a hardo!
