When your grades suddenly drop down randomly and goes back to normal the next few tests you take.
Spiking usually happens if either you are not keeping up to speed with the others in work or are not enjoying the type of lessons the teacher is giving you. (Sometimes the teacher can impact the entires class grades if she gets mad by a single person or a group of idiots in your class, so try and don't piss her off too much)

"I heard that Jack spiked one of his grades because of a bad day"
"I didn't do well today on the test, I'll try to get my grades back up as soon as possible so it counts as a spike"
"The girls in the back were being such a pain to the teacher today, hope she doesn't spike our whole class"

when you put excessive pictures of old people (particularly grans, if it is a males possesions)somewhere hidden for someone to find at a later date. usually in a possesion which wil be carried around, such as a wallet.
