In a game he will eliminate his enemy with
nades till he runs out, in games where he can "pick-up" more he will often chose a places to be on defense or offense based on the number of spawn points for nades.
a
nade whore may also use timing of spawns to nade a player who has spawned and he know will come back for him
a example of this is
Sniper frags enemy
*waits
7 seconds* tosses nade kills enemy
enemy: SPAMMER!!
sniper: no i timed you
