Drawing man, I get out first of crayons (8)
I believe the answer is:
magnetic
'drawing' is the definition.
(I've seen this before)
'man i get out first of crayons' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'first of crayons' becomes 'c' (1st letter of 'crayons').
'man'+'i'+'get'='maniget'
'maniget' anagrammed gives 'magneti'.
'magneti'+'c'='MAGNETIC'
(Other definitions for magnetic that I've seen before include "Having the property of attracting iron" , "Having the power to attract" , "Very attractive or alluring" , "What's attractive" , "Drawing" .)
