Bumptious bat's foul brew (8)

Ross

I believe the answer is:

boastful

I'm a little stuck... Click here to teach me more about this clue!

'bumptious' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I don't see?

'bat's foul brew' is the wordplay.
'brew' indicates an anagram.
'bats'+'foul'='batsfoul'
'batsfoul' anagrammed gives 'BOASTFUL'.

Can you help me to learn more?

(Other definitions for boastful that I've seen before include "Vainglorious" , "Immodest" , "Talking with excessive pride in one's own ability" , "Given to bragging, being conceited" , "Given to blowing one's own trumpet" .)
