Thingamagig
A Charity Music Festival which takes place every year in Billericay, Essex, UK to raise and funds for local charities.
I'm going to Thingamagig Festival at the weekend to watch my friend's band play and help charity.
Twerking Thingamagig
When an inanimate object is made to awkwardly dance. (usually is unintentionally creepy).
"Those dancing santas that come out around Christmas are some weird twerking thingamagigs."
