Cheeky bloke only just up (8)
I believe the answer is:
freshman
'only just up' is the definition.
I can't tell whether this defines the answer.
'cheeky bloke' is the wordplay.
'cheeky' becomes 'fresh' (I've seen this before).
'bloke' becomes 'man' (informal term for a man).
'fresh'+'man'='FRESHMAN'
Can you help me to learn more?
(Other definitions for freshman that I've seen before include "newly experiencing life in Jesus?" , "Young person" , "He's a first-year college student" , "He's a first-year undergraduate" , "First-year student in university, sounds like cheeky male" .)
