Forum:Activate during your Main Phase

Can "During your main phase;" effects be put on a chain? I'm used to playing Magic: The Gathering and was wondering if "During your main phase" is similar to "Only activate as a sorcery."

For example, if I play a trap card during an enemy's main phase in response to them playing a creature, can they use a monster's effect that can only be used "During your main phase"?
