a situation where the train of thought is blown off track. a teacher could call on a student expecting a question relating to the math topic and the student asks a question about something completely irrelevant.
Teacher: Does anyone not understand this example of the Pythagorean Theorem?
*student in front row raises his hand*
Teacher: Yes, Student?
Student: Why are their always girls in the hallways holding hands?
Student in the Back: You just got SAMERED!!
To be hammered, but more Sam-like. Usually people with the name Sam are more prone to becoming sammered, but it's quickly becoming very popular for anyone, regardless of their name to become sammered.
