#T-SQL, 84 bytes

DECLARE @ INT=1a:PRINT REPLICATE(SUBSTRING('conemon',@,1),2*@+8)SET @+=1IF @<8GOTO a

The variable/loop approach turned out shorter than the best set-based variation I came up with (91 bytes):

SELECT REPLICATE(SUBSTRING('conemon',n,1),2*n+8)FROM(VALUES(1),(2),(3),(4),(5),(6),(7))a(n)

I don't know what it is, but I found this question particularly annoying. Which probably means it's a good question.
